Prior to this commit,
`MockHttpServletRequest.isRequestedSessionIdValid()` would return `true`
by default and could only be changed manually with a setter. This does
not align with the Servlet spec because of 1) its default value and 2)
it does not react to `changeSessionId()` calls.
This commit fixes that behavior while still allowing "manual" booleans
being set here.

Previously, PropertyEditorRegistrySupport.addStrippedPropertyPaths()
recursively enumerated every combination of stripped/retained [key]
segments in a property path, producing 2^n - 1 variants for a path
with n bracket pairs.
To address that, this commit limits the recursion at a depth of 8,
preserving existing behavior for realistic property paths while
bounding the work done for paths with an unusually large number of
bracket segments.
Closes gh-37020
Previously, createMap() invoked createIndexedValue() – and therefore
createObject() for non-simple value types – once per matching parameter
name rather than once per distinct map key, causing redundant nested
object construction for map entries whose value type has multiple
constructor parameters.
To address that, this commit aligns createMap() with createList() and
createArray() by skipping construction for keys that have already been
resolved.

The builder method required a non-null contextPath while the underlying
field, MutatedServerHttpRequest constructor, and RequestPath.parse all
accept null and treat it the same as an empty string. Relax the method
parameter to @Nullable so callers can clear the context path directly.

When CglibAopProxy validates the target class, it logs a WARN-level
message for each public final method that implements an interface,
suggesting to use interface-based JDK proxies instead. For final
methods inherited from Spring's configuration callback interfaces
(InitializingBean, DisposableBean, Aware sub-interfaces, Closeable,
AutoCloseable) that recommendation is misleading: those methods are
container-driven, are not advised by typical application pointcuts, and
the user usually cannot make them non-final.
The validation now only emits the WARN-level message when at least one
user-defined interface declares the method. Methods inherited
exclusively from configuration callback interfaces fall back to the
existing DEBUG diagnostic.
In addition, the isConfigurationCallbackInterface() method has been
extracted from ProxyProcessorSupport into a static package-private
method in AopProxyUtils with the same signature, and
ProxyProcessorSupport and CglibAopProxy now delegate to the new shared
static utility in AopProxyUtils.

Since we now have an official builder API for SpelParserConfiguration
(introduced in 7.0.10), this commit follows through on the plan stated
in that commit's Javadoc and formally deprecates all 9 overloaded
constructors in SpelParserConfiguration, thereby encouraging users to
benefit from the simplicity of the builder API -- or
SpelParserConfiguration.withDefaults() for the common case -- instead
of having to migrate to the latest-and-greatest full constructor every
time a new configuration property is introduced.
The no-arg constructor points users to withDefaults(), and all other
constructors -- including the canonical 9-parameter constructor --
point to the builder API. Builder.build() has been annotated with
@SuppressWarnings("deprecation"), since it is the sole legitimate
internal caller of the now-deprecated canonical constructor.
The SpelParserConfigurationTests.LegacyConstructorTests nested class
(and its sibling builderAppliesSameDefaultsAsNoArgConstructor() test
method) are annotated with @SuppressWarnings("deprecation"), since they
exist specifically to provide regression coverage for the deprecated
constructors. IndexingTests.MaxAutoGrowSizeTests and
SpelParserTests.MaxNestingDepthTests, on the other hand, were both
introduced before the builder API existed and had no such need for the
legacy constructors, so they have been converted to use the builder API
instead, avoiding the need for any deprecation suppression there.
See gh-37187
Closes gh-37190
Prior to this commit, SpelParserConfiguration exposed 8 overloaded
constructors that accumulated over time as new configuration options
were introduced (auto-grow support since 3.0, maximumExpressionLength
in 5.2.25, maximumOperations in 6.2.19, and maximumBigPowerBits in
7.0.9), culminating in an 8-parameter constructor. This made call sites
hard to read due to unlabeled sequences of booleans and ints, and it
forced users who wanted to override a single setting to also supply
every other value explicitly.
To address that, this commit introduces a builder API in
SpelParserConfiguration, following the pattern already established by
SimpleEvaluationContext's builder API.
Specifically, SpelParserConfiguration.builder() returns a Builder that
is pre-populated with the same defaults as the no-arg constructor,
including the SpringProperties-driven overrides for the default
compiler mode, maximum operations, and maximum big-power bits -- the
latter two are only resolved lazily in build(), so that overriding them
via the builder never triggers an unnecessary SpringProperties lookup.
Each property has a dedicated, named setter (compilerMode(),
compilerClassLoader(), maximumAutoGrowSize(),
maximumExpressionLength(), maximumOperations(), maximumBigPowerBits()),
and the two auto-grow flags are exposed as simple no-arg opt-ins
(autoGrowNullReferences(), autoGrowCollections()) since they both
default to false. build() delegates to the existing canonical
constructor, so validation and defaults remain centralized in one
place.
In addition, a new SpelParserConfiguration.withDefaults() factory
method has been introduced as shorthand for
SpelParserConfiguration.builder().build(), for the common case where
none of the builder's defaults need to be overridden.
As the one deliberate exception to matching the no-arg constructor's
defaults, the builder defaults maximumAutoGrowSize to 256 -- aligned
with DataBinder.DEFAULT_AUTO_GROW_COLLECTION_LIMIT -- rather than the
constructors' Integer.MAX_VALUE. The constructors keep their legacy
default for backward compatibility, but the builder is a new, opt-in
API that is not bound by that compatibility contract.
This change is purely additive: none of the existing constructors have
been modified or deprecated. Deprecating those constructors in favor of
the builder is being deferred to 7.1, since new deprecations should not
be introduced in a patch release. In the meantime, the Javadoc for the
constructors and for the SPRING_EXPRESSION_*_PROPERTY_NAME constants
has been updated to favor the builder (or a specific Builder setter)
instead of the constructors, and the class-level Javadoc now states
that the constructors are planned to be deprecated in favor of the
builder as of Spring Framework 7.1.
SpelExpressionParser's no-arg constructor, ExpressionState's two
convenience constructors, and StandardBeanExpressionResolver's
ClassLoader-based constructor have all been switched from the
SpelParserConfiguration constructors to the builder (or
withDefaults()). This is behaviorally identical in every case:
autoGrowCollections remains false at each of those call sites, and
maximumAutoGrowSize -- the only property whose default differs between
the constructors and the builder -- has no effect when
autoGrowCollections is false.
Tests have been added in a new SpelParserConfigurationTests class to
verify that the builder's defaults match the no-arg constructor (with
the one intentional maximumAutoGrowSize exception called out above),
that custom values are applied correctly, and that invalid values are
rejected. The nested LegacyConstructorTests class provides regression
coverage for each of the legacy constructors, consolidating their usage
in tests to a single class -- which will keep any future deprecation
warnings confined to this class -- and documents that, unlike the
builder, the canonical constructor does not (yet) reject a negative
maximumAutoGrowSize. The remaining incidental usages of the
SpelParserConfiguration constructors throughout EvaluationTests,
IndexingTests, SpelCompilationCoverageTests, SpelReproTests, and
SpelCompilerTests have been converted to use the builder.
Furthermore, the reference documentation has been updated to recommend
the builder and withDefaults() over the constructors, both in prose and
in the Java/Kotlin examples.
Closes gh-37187
Prior to this commit, ConstructorReference.createArray() enforced the
MAX_ARRAY_ELEMENTS threshold for multi-dimensional arrays by checking
only the product of all dimension sizes, which is equivalent to the
total number of leaf-level elements. However, Array.newInstance()
allocates a distinct array object at every nesting level, not just at
the leaf level. For dimensions [d0, d1, ..., dk-1], the total number
of array objects created is 1 + d0 + d0*d1 + ... + d0*d1*...*d(k-2).
As a result, an expression such as new int[262143][1][1]...[1], whose
trailing dimensions are all 1, kept the leaf-element product just
under the threshold while still causing tens of millions of array
objects to be allocated.
To address that, this commit introduces a second running total,
totalArrayObjects, alongside the existing leaf-element product in the
multi-dimensional array construction loop. Both totals are checked
against MAX_ARRAY_ELEMENTS on every iteration, so array constructions
that fan out into an excessive number of array objects are now
rejected even when the leaf-element count remains within bounds.
Note that SimpleEvaluationContext does not permit array construction
in SpEL expressions at all, so this fix effectively only changes
behavior for expressions evaluated via StandardEvaluationContext.
Tests have been added to ArrayConstructorTests to verify that the new
check rejects array constructions with an excessive number of array
objects and that array constructions just under the threshold remain
unaffected.
Closes gh-36998
Prior to this commit, the SpelParserConfiguration constructors that
omit an explicit maximumAutoGrowSize left collection auto-growing
effectively unbounded, defaulting to Integer.MAX_VALUE. That default
was inconsistent with the auto-grow limit applied elsewhere in the
framework for data binding (see
DataBinder.DEFAULT_AUTO_GROW_COLLECTION_LIMIT).
To address that, this commit introduces a new
SpelParserConfiguration.DEFAULT_MAX_AUTO_GROW_SIZE constant (set to 256
to match DataBinder.DEFAULT_AUTO_GROW_COLLECTION_LIMIT) and switches
the constructors that previously hard-coded Integer.MAX_VALUE to use
this new default instead. Constructors that accept an explicit
maximumAutoGrowSize are unaffected.
In addition, SpelParserConfiguration now enforces that a user-supplied
maximumAutoGrowSize is not a negative value, consistent with the
preconditions already enforced for maximumExpressionLength,
maximumOperations, maximumBigPowerBits, and maximumNestingDepth. A
value of 0 remains supported (effectively disabling collection
auto-growing) and is now documented as such in the Javadoc.
The Spring Framework reference documentation has also been updated to
describe the new default, and tests have been added to IndexingTests to
verify the default, the ability to override it, and the new
precondition.
Closes gh-36995
This commit introduces support for limiting the structural nesting
depth of a SpEL expression during parsing. Without such a limit, an
expression with deeply nested constructs (for example, inline lists or
maps, parenthesized expressions, ternary or Elvis expressions, or
chained unary operators) can cause SpEL's recursive-descent parser to
throw a StackOverflowError which lacks useful diagnostics for
developer's attempting to assess what went wrong.
With this commit, a nesting-depth counter is now tracked around the
parser's primary recursive entry point (eatExpression()) as well as
around chained unary operators (eatUnaryExpression()), ensuring that
independent, sibling uses of assignment, Elvis, and ternary expressions
do not inadvertently accumulate depth and trip the limit.
If the configured (or default) nesting-depth limit is exceeded during
parsing, a SpelParseException is thrown instead, with a message that
reports the configured limit.
The limit can be configured on a per-use-case basis via
SpelParserConfiguration and defaults to 1000.

In commit 622fc3edf7, I introduced a check in
TypeMappedAnnotation#isSynthesizable() intended to force synthesis when
an attribute value needs to be resolved from a different level of a
multi-level annotation hierarchy whose root annotation does not
redeclare the target attribute itself.
That check tested if `resolvedMirrors.length > 0` for a
meta-annotation; however, resolvedMirrors is always sized according to
the number of attributes declared by the mapped annotation type,
regardless of whether any of those attributes actually participate in
mirroring or an @AliasFor override. As a result, the check effectively
synthesized any meta-annotation that declares at least one attribute,
which reintroduced the unnecessary-synthesis behavior that commit
d6768ccc18 had fixed, merely narrowed to meta-annotations with
attributes.
This commit replaces that overly broad check with a precise one in
AnnotationTypeMapping#computeSynthesizableFlag(), which now also
considers whether any attribute's value must be resolved from a
different annotation in the meta-annotation hierarchy (tracked via
annotationValueSource). This correctly identifies the original
multi-level hierarchy scenario without over-matching on ordinary
meta-annotations that have nothing to merge or override.

OptionalToObjectConverter.matches() used
TypeDescriptor.getElementTypeDescriptor(), which returns null for an
Optional (element types are only resolved for arrays, streams and
collections). ConversionUtils.canConvertElements() then treats a null
source element type as "maybe" and returns true unconditionally, so
ConversionService.canConvert(Optional<X>, target) reported true even
when X is not convertible to the target -- a violation of the
canConvert contract, since the subsequent conversion fails.
To address that, this commit resolves the Optional's element type from
its generic and checks it against the target, mirroring
ObjectToOptionalConverter. A raw or otherwise unresolved element type
remains permissive.

Excluding a path from nohttp scanning has so far required mirroring it
by hand in CheckstyleConventions, in addition to any existing
`.gitignore` entry. However, that extra step is easy to forget, as
happened when the .claude folder was added to `.gitignore` (49d2a202da)
but not to the nohttp excludes (48971139c0), only surfacing later as
an OutOfMemoryError that required a separate heap size increase
(90ad7f947d).
To address that, this commit introduces excludeGitIgnoredPaths() in
CheckstyleConventions, which parses the root `.gitignore` file and
translates its patterns into additional nohttp excludes, so that newly
ignored paths are picked up automatically. Note, however, that the
existing hand-maintained excludes are left in place for entries that
are specific to nohttp and are not otherwise ignored by git.

Prior to this commit, some same-page links in our Antora-based docs
were written using the `xref:` macro, which Antora resolves as a
cross-page reference. However, a same-page target can be misread as a
page reference and break the site build (as nearly happened in
gh-37152), whereas `<<id,text>>` only ever resolves against the current
page's own anchors.
To address that inconsistency and avoid potential future bugs (broken
links), this commit converts all such same-page `xref:` links to
`<<id,text>>`, leaving genuine cross-page `xref:` links are unaffected.

On a developer machine, the nohttp check scans the whole project
directory, and things like local git worktrees can add enough extra
content on disk to push the task past its previous 1g heap limit,
causing an OutOfMemoryError. This goes beyond what was addressed by
excluding the .claude folder from nohttp scanning in 48971139c0.
This commit raises the heap size for checkstyleNohttp specifically
to 1536m, leaving the limit for other Checkstyle tasks unchanged so
as not to increase memory pressure on CI.
Prior to this commit, Property.resolveName() located the "set" prefix
of a write method with String.indexOf(), which matches the token
anywhere in the method name. A write method that merely contains "set"
(for example "offsetX" or "upset") was silently accepted and resolved
to a meaningless property name derived from whatever follows the token,
while only names with no "set" token at all were rejected.
To address that, this commit matches the "set" prefix only at the start
of the method name via startsWith(), so that an
IllegalArgumentException is consistently thrown for any write method
candidate that is not a setter.

Property.resolveName() located the get/is accessor prefix with
String.indexOf, which matches the prefix anywhere in the method name.
A plain accessor whose name embeds such a prefix (for example
budget()) had the wrong portion stripped and resolved to an empty or
wrong property name, which in turn caused the backing field's
annotations to be silently dropped.
Match the get/is prefix only at the start of the method name and do
not strip it when the method is a plain accessor for a data class,
that is, a non-static no-arg method referring to an instance field of
the same name. This supports Java records, Kotlin data classes, and
custom Java data classes alike, without relying on java.lang.Record.
As a consequence, a getter backed by a field of the exact same name
(for example isUrgent()) now resolves to the field name.

ReflectivePropertyAccessor's canRead(), read(), and canWrite() methods
previously constructed org.springframework.core.convert.Property
instances without an explicit name, forcing Property#resolveName() to
re-derive the property name from the accessor method via prefix
matching. That heuristic incorrectly resolves record-style and other
prefix-less accessor methods whose names embed or start with "get"/"is"
(for example, budget(), issue(), or island()), and it also normalizes
acronym-style JavaBean properties inconsistently (for example, getURL()
resolves to "uRL" rather than "URL").
By the time these three methods construct a Property, they have already
located the accessor method by searching for exactly the requested
property name, so the resolved name is already known and verified. This
commit passes that name through explicitly via the 4-arg Property
constructor, bypassing Property#resolveName() entirely at these call
sites.
This commit also introduces tests in PropertyAccessTests to cover the
following scenarios:
- A genuine record accessor whose component name embeds or starts with
a "get"/"is" prefix
- The same scenario on a hand-written, non-record "data class"
- The read() call site exercised directly, since it is otherwise
unreachable once canRead() has warmed the cache
- A boolean isXxx() getter, as a plain regression check
- An acronym-style property with a decoy field to prove that the
correct field (and its annotations) is now resolved for both reads
and writes
