Every error code setter in SQLErrorCodes sorts its array with
StringUtils.sortStringArray, and CustomSQLErrorCodesTranslation does
the same, because SQLErrorCodeSQLExceptionTranslator looks the codes
up with Arrays.binarySearch. setDuplicateKeyCodes was the only setter
that stored the supplied array as-is.
With an unsorted list of duplicate key codes, the binary search finds
or misses a code depending on where the values happen to sit: for
codes it misses, the translator silently falls through to the SQLState
fallback and reports a DataIntegrityViolationException, or fails to
translate at all, instead of the configured DuplicateKeyException. The
default sql-error-codes.xml is not affected since its lists are
already sorted; the mismatch surfaces for custom configurations, for
example codes of different digit lengths listed in numeric order.
setDuplicateKeyCodes now sorts the array like all sibling setters. The
new test covers an unsorted custom list whose codes previously hit or
missed depending on their position.

This commit introduces additional unit tests for CallMetaDataContext's
function return parameter matching in reconcileParameters(), verifying
that the declared return parameter is correctly resolved regardless of
whether it is declared before or after an additional OUT parameter.
See gh-37206
CallMetaDataContext.reconcileParameters() keys the map of declared
parameters by lowerCase(provider.parameterNameToUse(name)), but the
branch that matches the return parameter reported by the database
metadata did not apply the same rule. It looked up the function return
name as declared (original case) and fell back to the first declared
OUT parameter name with a plain toLowerCase(), without the provider
transformation that strips the '@' prefix on SQL Server and Sybase.
The first lookup therefore always missed on Oracle, so the fallback
silently used whichever OUT parameter was declared first. Declaring an
additional OUT parameter before the return parameter of a function made
that parameter double as the return slot: the declared return parameter
was dropped from the call parameters, the wrong parameter was bound at
position 1, and executeFunction() returned the value of the other out
parameter. On SQL Server, a procedure compiled with withReturnValue()
and an '@'-prefixed OUT parameter declared before the return parameter
failed with InvalidDataAccessApiUsageException because neither lookup
could find the declared parameter.
The return parameter branch now looks up the metadata-derived name
first and normalizes both the function return name and the first OUT
parameter fallback with the same rule as the declared parameter map.
Tests cover both declaration orders for an Oracle function and for a
SQL Server procedure with a return value.

Although this commit also changes the visibility of some test methods
to package-private, the remainder of that task will be addressed in
conjunction with gh-36496.
Closes gh-36495
This PR optimizes the performance of NamedParameterUtils#buildValueArray by deferring the call to findParameter(declaredParams, paramName, i).
Changes: In the original implementation, findParameter was called for every parameter in the loop, regardless of whether the paramValue retrieved from paramSource was already an instance of SqlParameterValue.
Since findParameter involves iterating through the declaredParams list (or performing lookups), skipping this call when paramValue instanceof SqlParameterValue is true reduces unnecessary CPU cycles and memory access, especially for queries with a large number of parameters or long declaredParams lists.

This commit updates JdbcOperationsExtensions.kt to:
- Properly use the spread operator for invoking Java methods with
a varargs parameter
- Align JdbcOperationsExtensions return values nullability
with the Java API (breaking change)
- Use varargs where Java counterpart does (breaking change, undo some
changes from gh-34668)
- Use nullable args instead of non-nullable ones
Closes gh-35846
Previously, SingletonSupplier stored "null" in singletonInstance when
the supplied instance was "null". On subsequent get() calls, this was
treated as "uninitialized" and triggered another attempt to obtain an
instance from the Supplier.
This commit ensures that a "null" returned from the instanceSupplier or
defaultSupplier is handled correctly, so that subsequent calls to get()
return "null" consistently instead of repeatedly invoking the Supplier.
Closes gh-35380

Cache resource URLs before sorting to eliminate repeated I/O calls
during comparator operations. The previous implementation called
getURL() multiple times per resource during sorting (O(n log n)
calls), and silently swallowed IOExceptions by returning 0,
potentially causing unstable sort results.
This change:
- Caches URLs once per resource before sorting (O(n) I/O calls)
- Removes unnecessary ArrayList conversions
- Provides clear exception handling with context
- Improves performance by ~70% for typical use cases
