Spring Framework 5.0 introduced a regression in ASM-based annotation
processing. Specifically, nested annotations were no longer supported,
and component scanning resulted in an exception if a candidate
component was annotated with an annotation that contained nested
annotations.
This commit fixes this regression by introducing special handling in
AnnotationTypeMapping that supports extracting values from objects of
type TypeMappedAnnotation when necessary.
Closes gh-24375
This is a follow-up on the earlier commit
28a95e89f3 eliminating windowUntil
entirely which generates a BubblingException wrapper. This also keeps
the chain a little simpler.

Spring Framework provides two implementations of the
CommandLinePropertySource API: SimpleCommandLinePropertySource and
JOptCommandLinePropertySource.
Prior to this commit, JOptCommandLinePropertySource supported empty
values for optional arguments; whereas, SimpleCommandLinePropertySource
did not.
This commit modifies the implementation of SimpleCommandLinePropertySource
to allow empty values for optional arguments.
Closes gh-24464
The case of one data buffer containing multiple lines can could cause
a buffer leak due to a suspected issue in concatMapIterable. This
commit adds workarounds for that until the underlying issue is
addressed.
Closes gh-24339
Given the following improperly configured composed @RequestMapping
annotation:
@Retention(RetentionPolicy.RUNTIME)
@RequestMapping
@interface PostApi {
@AliasFor("value")
String[] path() default {};
@AliasFor(annotation = RequestMapping.class, attribute = "path")
String[] value() default {};
}
Prior to this commit, an attempt to process the above annotation
resulted in an exception similar to the following, which is not
especially helpful to discern the problem.
> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor 'path', not 'path'.
This commit improves the exception message for such scenarios,
resulting in an exception message similar to the following.
> Attribute 'value' in annotation [PostApi] must be declared as an
> @AliasFor attribute 'path' in annotation [PostApi], not attribute
> 'path' in annotation [RequestMapping].
Closes gh-24168
Update `ResolvableType` so that variable referenced can be resolved
against wildcard types. Prior to this commit, given a type:
Map<String, ? extends List<? extends CharSequence>>
Calling `type.getGeneric(1).asCollection().resolveGeneric()` would
return `null`. This was because the `List` variable `E` referenced a
wildcard type which `resolveVariable` did not support.
Closes gh-24145
Spring Framework 5.2 introduced a regression for implicit aliases
declared via @AliasFor. Specifically, Spring's merged annotation
algorithms stopped honoring default values for implicit alias pairs if
the composed annotation was used without specifying the aliased
attributes.
This commit fixes this regression.
Closes gh-24110
Spring Framework 5.2 introduced a regression in reflection-based
AnnotationMetadata. Specifically, as of 5.2, StandardAnnotationMetadata
no longer found @Inherited annotations from superclasses.
This commit fixes this regression by switching to the INHERITED_ANNOTATIONS
SearchStrategy when creating the MergedAnnotations used within
StandardAnnotationMetadata,
Note, however, that the discrepancy between StandardAnnotationMetadata
and SimpleAnnotationMetadata (i.e., reflection-based vs. ASM-based)
regarding @Inherited support still remains as it was prior to Spring
Framework 5.2.
Closes gh-24077
This commit introduces failing assertions that are currently disabled
via a boolean reproduceGh24077 flag.
Setting that flag to true demonstrates the regression for
StandardAnnotationMetadata and inconsistencies for SimpleAnnotationMetadata.
See gh-24077
