Rework AnnotatedElementAdapter to avoid cloning the underlying
Annotation array if it is empty when getAnnotations() is called.
Additionally, make the class static and add a factory method that
returns a singleton instance for null or empty Annotation arrays.

KClass instantiation in CoroutinesUtils is suboptimal, and should be
replaced by KTypes#isSubtypeOf checks using pre-instantiated types for
Flow, Mono and Publisher.
This commit impact on performances is significant since a throughput
increase between 2x and 3x has been measured on basic endpoints.
Closes gh-32390
To smooth upgrade from 6.1.x, this commit makes sure that code that used
to catch an IAE to ignore a faulty placeholder resolution still works.
See gh-9628
This commit fixes a performance regression caused by gh-31698,
and more specifically by KClass#isValue invocations which are slow since
they load the whole module to find the class to get the descriptor.
After discussing with the Kotlin team, it has been decided that only
checking for the presence of `@JvmInline` annotation is enough for
Spring use case.
As a consequence, this commit introduces a new
KotlinDetector#isInlineClass method that performs such check, and
BeanUtils, CoroutinesUtils and WebMVC/WebFlux InvocableHandlerMethod
have been refined to leverage it.
Closes gh-32334
This commit introduces composite collections (i.e. Collection, Set, Map)
and uses these composites in request predicates, where before new
collections were instantiated.
Closes gh-32245
Add helpers to CollectionUtils for building HashSets and LinkedHashSets
that can hold an expected number of elements without needing to
resize/rehash.
Closes gh-32291
In places where a ConcurrentHashMap was used as a set by wrapping it
with Collections.newSetFromMap, switch to just using the set returned
by ConcurrentHashMap.newKeySet directly.
Closes gh-32294
Delegate to the spliterator method of the underlying collection in
MutablePropertyValues and MutablePropertySources. In both cases, those
collection types have specialized Spliterator implementations.
Delegating to these Spliterators also means the characteristics of the
Spliterator are properly set.

This commit removes the previous implementation in favor of the new
PlaceholderParser. The only noticeable side effect is that the exception
is no longer an IllegalArgumentException, but rather the dedicated
PlaceholderResolutionException.
See gh-9628
This commit provides a rewrite of the parser for properties containing
potentially placeholders.
Assuming a source where `firstName` = `John` and `lastName` = `Smith`,
the "${firstName}-${lastName}" property is evaluated as "John-Smith".
Compared with the existing implementation in PropertyPlaceholderHelper,
the new implementation offers the following extra features:
1. Placeholder can be escaped using a configurable escape character.
When a placeholder is escaped it is rendered as is. This does apply to
any nested placeholder that wouldn't be escaped. For instance,
"\${firstName}" is evaluated as "${firstName}".
2. The default separator can also be escaped the same way. When the
separator is escaped, the left and right parts are not considered as
the key and the default value respectively. Rather the two parts
combined, including the separator (but not the escape separator) are
used for resolution. For instance, ${java\:comp/env/test} is looking
for a "java:comp/env/test" property.
3. Placeholders are resolved lazily. Previously, all nested placeholders
were resolved before considering if a separator was present. This
implementation only attempts the resolution of the default value if the
key does not provide a value.
4. Failure to resolve a placeholder are more rich, with a dedicated
PlaceholderResolutionException that contains the resolution chain.

Prior to this commit, the `SimpleCommandLineArgsParser` would reject
"--" arguments as invalid. As reported by the community, the POSIX
utility conventions (Guideline 10) state that
> The first -- argument that is not an option-argument should be
> accepted as a delimiter indicating the end of options.
> Any following arguments should be treated as operands, even if they
> begin with the '-' character.
This commit updates `SimpleCommandLineArgsParser` to not reject "--"
arguments and instead to consider remaining arguments as non-optional.
See gh-31513
This notably enables Jackson to reflectively call a user-provided
builder class and invoke its declared methods (setters and build) in
a native app.

Schedulers remain strict, just plain executors are lenient on shutdown now.
An early shutdown for executors can be enforced via setStrictEarlyShutdown.
Closes gh-32226
To improve consistency and avoid confusion regarding primitive types
and their wrapper types, this commit ensures that we always use class
literals for primitive types.
For example, instead of using the `Void.TYPE` constant, we now
consistently use `void.class`.
Prior to this commit, the alias resolution error message in
SimpleAliasRegistry was misleading.
When a resolution conflict is detected, the IllegalStateException
thrown by resolveAliases(...) now states that the resolved alias is
already registered for an `existingName` instead of the `registeredName`.
See gh-31353
Closes gh-32025
This commit improves SimpleAliasRegistryTests in the following ways.
- Some existing methods have been split up into smaller test methods
which focus on a single use case.
- The use of Mockito mocks has been replaced by a hand-crafted
StubStringValueResolver which ensures that existing aliases and names
are not accidentally replaced by null thereby removing their removing
there mappings inadvertently.
- Several test methods now include inline comments that document the
current state of the aliasMap in order to clarify what is happening
behind the scenes in the ConcurrentHashMap.
- Several test methods warn that the current expectations are based on
ConcurrentHashMap iteration order!
- New @ParameterizedTest which is currently @Disabled but
demonstrates that complex use cases involving placeholder replacement
can be supported consistently -- regardless of the values of the
aliases involved -- but only if alias registration order is honored.
Closes gh-31353
This is able to resolve the original method even if no bridge method has been generated at the same class hierarchy level (a known difference between the Eclipse compiler and regular javac).
