Prior to this commit, the new match algorithm wouldn't work for multiple
consecutive path separators.
This commit separately matches path segments and path separators and
allows for multiple, consecutive path separators.

This commit documents the @Ignore'd test to explain that Spring does not
support a hybrid approach for annotation attribute overrides with
transitive implicit aliases.
Issue: SPR-13554
This commit introduces a boolean alwaysProcesses() method in the
Processor API which allows for simplification across all search
algorithms within AnnotatedElementUtils.
Specifically, it is no longer necessary for process() methods to verify
that the supplied annotation is actually the sought target annotation.
In addition, duplicated code has been extracted into common methods
(e.g., hasMetaAnnotationTypes()) and common Processor implementations
(e.g., AlwaysTrueBooleanAnnotationProcessor).
This commit picks up where 2535469099 left off with added support for
"get" search semantics for merged repeatable annotations.
Specifically, this commit introduces a new
getMergedRepeatableAnnotations() method in AnnotatedElementUtils.
Issue: SPR-13973
This commit picks up where a5139f3c66 left off with added support for
"get" search semantics for multiple merged annotations.
Specifically, this commit introduces a new getAllMergedAnnotations()
method in AnnotatedElementUtils.
Issue: SPR-13486
Prior to this commit, AnnotationUtils supported searching for
repeatable annotations even if the repeatable annotation was declared
on a custom stereotype annotation. However, there was no support for
merging of attributes in composed repeatable annotations. In other
words, it was not possible for a custom annotation to override
attributes in a repeatable annotation.
This commit addresses this by introducing
findMergedRepeatableAnnotations() methods in AnnotatedElementUtils.
These new methods provide full support for explicit annotation
attribute overrides configured via @AliasFor (as well as
convention-based overrides) with "find semantics".
Issue: SPR-13973
Prior to this commit it was possible to search for the 1st merged
annotation above an annotated element. It was also possible to search
for annotation attributes aggregated from all annotations above an
annotated element; however, it was impossible to search for all
composed annotations above an annotated element and have the results as
synthesized merged annotations instead of a multi-map of attributes.
This commit introduces a new findAllMergedAnnotations() method in
AnnotatedElementUtils that finds all annotations of the specified type
within the annotation hierarchy above the supplied element. For each
such annotation found, it merges that annotation's attributes with
matching attributes from annotations in lower levels of the annotation
hierarchy and synthesizes the results back into an annotation of the
specified type. All such merged annotations are collected and returned
as a set.
Issue: SPR-13486
This commit introduces tests that verify the status quo for finding
multiple merged composed annotations on a single annotated element.
Issue: SPR-13486
Prior to this commit, it was possible that implicit aliases and
transitive implicit aliases (configured via @AliasFor) might not be
honored in certain circumstances, in particular if implicit aliases
were declared to override different attributes within an alias pair in
the target meta-annotation.
This commit addresses this issue by ensuring that all aliased
attributes in the target meta-annotation are overridden during the
merge process in AnnotatedElementUtils.
In addition, concrete default values for attributes in a
meta-annotation declaration can now be effectively shadowed by
transitive implicit aliases in composed annotations.
Issue: SPR-14069
This commit picks up where 8ff9e818a5
left off.
Specifically, this commit introduces support that allows a single
element attribute to override an array attribute with a matching
component type when synthesizing annotations (e.g., in annotations
synthesized from attributes that have been merged from the annotation
hierarchy above a composed annotation).
Issue: SPR-13972
Refine the optimizations made in 6f55ab69 in order to restore binary
compatibility and resolve a regression.
Tests of the form pathMatcher.match("/foo/bar/**", "/foo/bar") should
return true as this was the behavior in Spring 4.2.
Issue: SPR-13913
This commit speeds up the AntPathMatcher implementation by
pre-processing patterns and checking that candidates are likely
matches if they start with the static prefix of the pattern.
Those changes can result in a small performance penalty for positive
matches, but with a significant boost for checking candidates that don't
match. Overall, this tradeoff is acceptable since this feature is often
used to select a few matching patterns in a much bigger list.
This will lead to small but consistent performance improvements in
Spring MVC when matching a given request with the available routes.

JIRA: https://jira.spring.io/browse/SPR-13784
JDK8 and Apache Commons Codec support the RFC 4648
"URL and Filename Safe" Base64 alphabet.
Add methods to `Base64Utils` to support this feature.
This commit migrates all remaining tests from JUnit 3 to JUnit 4, with
the exception of Spring's legacy JUnit 3.8 based testing framework that
is still in use in the spring-orm module.
Issue: SPR-13514
This commit picks up where 3eacb837c2
(SPR-13345) left off by adding support for transitive implicit aliases
configured via @AliasFor.
Issue: SPR-13405
Spring Framework 4.2 introduced support for aliases between annotation
attributes that fall into the following two categories.
1) Alias pairs: two attributes in the same annotation that use
@AliasFor to declare that they are explicit aliases for each other.
2) Meta-annotation attribute overrides: an attribute in one annotation
uses @AliasFor to declare that it is an explicit override of an
attribute in a meta-annotation.
However, the existing functionality fails to support the case where two
attributes in the same annotation both use @AliasFor to declare that
they are both explicit overrides of the same attribute in the same
meta-annotation. In such scenarios, one would intuitively assume that
two such attributes would be treated as "implicit" aliases for each
other, analogous to the existing support for explicit alias pairs.
Furthermore, an annotation may potentially declare multiple aliases
that are effectively a set of implicit aliases for each other.
This commit introduces support for implicit aliases configured via
@AliasFor through an extensive overhaul of the support for alias
lookups, validation, etc. Specifically, this commit includes the
following.
- Introduced isAnnotationMetaPresent() in AnnotationUtils.
- Introduced private AliasDescriptor class in AnnotationUtils in order
to encapsulate the parsing, validation, and comparison of both
explicit and implicit aliases configured via @AliasFor.
- Switched from single values for alias names to lists of alias names.
- Renamed getAliasedAttributeName() to getAliasedAttributeNames() in
AnnotationUtils.
- Converted alias map to contain lists of aliases in AnnotationUtils.
- Refactored the following to support multiple implicit aliases:
getRequiredAttributeWithAlias() in AnnotationAttributes,
AbstractAliasAwareAnnotationAttributeExtractor,
MapAnnotationAttributeExtractor, MergedAnnotationAttributesProcessor
in AnnotatedElementUtils, and postProcessAnnotationAttributes() in
AnnotationUtils.
- Introduced numerous tests for implicit alias support, including
AbstractAliasAwareAnnotationAttributeExtractorTestCase,
DefaultAnnotationAttributeExtractorTests, and
MapAnnotationAttributeExtractorTests.
- Updated Javadoc in @AliasFor regarding implicit aliases and in
AnnotationUtils regarding "meta-present".
