Request predicates support preflight request matching based on the "would be"
request (e.g. target HTTP method) so the actual handler is not meant to be
invoked. That's the case only with a DispatcherHandler setup.

Prior to this commit, SpEL expression compilation could be silently
activated in a SimpleEvaluationContext via the
`spring.expression.compiler.mode` Spring/system property or
SpelParserConfiguration. Once an expression is compiled, the evaluation
guards enforced during interpreted evaluation are no longer applied,
which is at odds with the restricted intent of SimpleEvaluationContext.
To address that, this commit introduces a mechanism analogous to
isAssignmentEnabled() which disables compilation by default in
SimpleEvaluationContext. Specifically:
- A new isCompilationSupported() default method has been introduced in
the EvaluationContext API, which returns true by default.
- SimpleEvaluationContext overrides isCompilationSupported() to return
false by default. However, compilation can be opted into explicitly
via the new withCompilationSupported() method in the
SimpleEvaluationContext.Builder.
- SpelExpression.checkCompile() now consults isCompilationSupported()
before triggering new compilation, ensuring that evaluation within an
EvaluationContext never produces a compiled form of the expression if
the context's isCompilationSupported() method returns false.
- All eight getValue() variants in SpelExpression now consult
isCompilationSupported() before executing a compiled expression,
ensuring that a compiled expression produced via a different
EvaluationContext is not silently reused if the caller inadvertently
switches to an EvaluationContext that does not support compilation.
Closes gh-37035
This commit introduces a configurable limit on the estimated result size
of BigDecimal and BigInteger power operations within SpEL expressions.
The estimated result size in bits is computed as the product of the base
value's bit length and the exponent. If this limit is exceeded, a
SpelEvaluationException is thrown.
The limit defaults to 1,000,000 bits, which is approximately equivalent
to a decimal number with 300,000 digits, and can be configured either
on a per-use-case basis via the new maximumBigPowerBits constructor
argument in SpelParserConfiguration or globally as a JVM system
property or Spring property named `spring.expression.maxBigPowerBits`.
Parsers intended for trusted internal expressions may supply
Integer.MAX_VALUE to remove the limit entirely.

Prior to this commit, the List branch in
AbstractNestablePropertyAccessor's getPropertyValue() method called
list.get(index) unconditionally after invoking
growCollectionIfNecessary(), which implicitly relied on the list
throwing an IndexOutOfBoundsException for out-of-range access. Such an
exception is caught downstream and wrapped as an
InvalidPropertyException; however, any List implementation whose get()
method allocates elements on demand rather than throwing an
IndexOutOfBoundsException could bypass that check.
This behavior was also inconsistent with the Collection/Iterable branch
in the same method, which already performs an explicit `index >=
collection.size()` bounds check before attempting element access.
To address that, this commit aligns the List branch with the
Collection/Iterable branch by adding an explicit `index < 0 || index >=
list.size()` check immediately after the auto-grow attempt. If the
index remains out of bounds after growCollectionIfNecessary() runs –
for example, because growth was capped by autoGrowCollectionLimit or
auto-growing was disabled – an InvalidPropertyException is now thrown
rather than delegating to list.get() which may or may not throw an
exception.

Prior to this commit, many classes would support writing Server Sent
Events in some way to the response output stream. This has lead to some
code duplication.
This commit refactors the duplicated code in a shared `SseUtils` class.

Prior to this commit, building a "Content-Disposition" header to a
String and then parsing it back would not always result in the original
header.
This commit ensures that ContentDisposition guarantees this and honors
the "equals" contract.

Prior to this commit, the MVC and WebFlux view fragments rendering would
only partially escape rendered view fragments before sending then as SSE
events. This could in some cases break the SSE stream with invalid data.
This commit ensures that the rendered views are properly escaped before
they are sent as SSE events.

A user reported confusion between two distinct uses of "wraps" in the
AOP proxy documentation for Bean Overrides: the sense in which a
Mockito spy wraps the original bean instance it was created from, and
the sense in which a Spring AOP proxy wraps the spy in the actual
object graph.
To address that, this commit adds two small diagrams to the general
"Bean Overrides and Spring AOP Proxies" section, illustrating, from a
caller's perspective, the shape of the bean for the
REPLACE/REPLACE_OR_CREATE strategy (no proxy at all) versus the WRAP
strategy (an AOP proxy still created, now wrapping the override
instance instead of the original bean). Both diagrams use the same
generic "override instance" label, since the section is not specific to
Mockito; a Mockito spy created by @MockitoSpyBean is mentioned only as
an example.
The accompanying text is revised to reserve "wraps" for the AOP proxy
relationship and to explicitly call out that a Mockito spy's
relationship to its original bean instance is a separate concern from
AOP proxy nesting.
The @MockitoSpyBean-specific strategy paragraph in the
@MockitoBean/@MockitoSpyBean documentation has also been revised
similarly, and now points to the new diagram.

This commit documents how the Bean Override support in the TestContext
framework interacts with Spring AOP proxies created for annotations
such as @Transactional, @Cacheable, and @Retryable.
The new "Bean Overrides and Spring AOP Proxies" section in the general
Bean Overriding documentation explains that overrides using the WRAP
strategy (such as @MockitoSpyBean) end up as the target of any AOP
proxy subsequently created for the original bean; whereas, overrides
using the REPLACE or REPLACE_OR_CREATE strategy (such as @TestBean,
@MockitoBean) bypass the container's bean post-processing entirely and
therefore carry no AOP advice at all.
The new "@MockitoSpyBean and Spring AOP Proxies" section documents the
resulting stubbing and verification semantics. Verification via
Mockito's verify() API works transparently regardless of whether it is
invoked on the proxy or on the spy. Stubbing via doReturn(...)/doThrow(...)
is safe for stateless advice such as @Retryable, but can silently
corrupt the spy's configured answers for stateful or memoizing advice
such as @Cacheable, since the invocation used to declare a stub is
intercepted by Mockito before it reaches the spy and returns an empty
value that such advice may then cache.
AopTestUtils.getUltimateTargetObject(...) is documented as the way to
stub directly against the spy in that case.
The same section also documents how to disable the AOP advice for a
test altogether while leaving it in place in production code – for
example, binding a @Retryable attribute to a property placeholder
overridden via @TestPropertySource, or replacing the CacheManager with
a NoOpCacheManager via @TestBean.
Brief cross-referencing notes have also been added to the @TestBean
documentation and to the existing AopTestUtils description in the
"General Testing Utilities" section, to avoid duplicating the
explanation across pages.
In addition, the Javadoc for @MockitoSpyBean now contains a concise
WARNING summarizing these AOP proxy implications and linking to the new
reference documentation section for details.

Prior to this commit, `HttpMessageConverterExtractor` was deprecated
with `RestTemplate` and related types. `StatusHandler` was still using
it and causing a deprecation warning.
This commit extracts the relevant implementation from
`DefaultRestClient` and promotes it as a shared static method in
`RestClientUtils`.
Fixes gh-37010
Prior to this commit, `DefaultExchangeFunction.exchange` added
logging operations within `doOnRequest`/`doOnCancel` operators
unconditionally, which costs two subscriber wrappers per request
even though the log message construction itself is already
guarded lazily. This commit gates the operators on `isDebugEnabled()`,
checked per exchange so runtime log level changes are still honored.

DataBufferUtils.TwoByteMatcher inherited AbstractNestedMatcher.match(byte)
without providing the mismatch fallback that its siblings implement
(KnuthMorrisPrattMatcher backtracks via its suffix-prefix table, and
SingleByteMatcher is stateless). As a result, once the first delimiter
byte had matched, the match counter stayed at 1 across any number of
intervening non-matching bytes, so a later occurrence of the second
delimiter byte falsely completed the match.
For a two-byte delimiter such as \r\n this made the matcher report a
match across non-contiguous bytes. CompositeMatcher prefers the longest
delimiter that matches at a position, so the false \r\n match was chosen
over a real single \n, causing StringDecoder to strip two bytes and drop
the character preceding a lone \n whenever a line contained a stray \r.
TwoByteMatcher now overrides match(byte) to reset the counter to 0 when
the incoming byte is not the expected next delimiter byte before
delegating to super.match(), mirroring KnuthMorrisPrattMatcher. A
genuine contiguous delimiter is unaffected.

ClassFileAnnotationDelegate passed the raw java.lang.classfile
Annotation to MergedAnnotation.of() as the annotation source. That
annotation holds a Utf8Entry, so retaining the metadata of an
annotated class also retained its class file byte[], the parsed
constant pool, and the class model.
Store the declaring class name instead, as the ASM variant does.
