This change adds a new `getDateHeader` method that converts date header
Strings to long values - making tests more readable.
This feature is also documented in the "what's new section" for 4.2.
Prior to this commit, requests with an empty body and no Content-Type
header set would fail with a HttpMediaTypeNotSupportedException when
mapped to a Controller method argument annotated with
@RequestBody(required=false).
In those cases, the server implementation considers with an
"application/octet-stream" content type and polls messageconverters for
conversion. If no messageconverter is able to process this request, a
HttpMediaTypeNotSupportedException is thrown.
This change makes sure that such exceptions are not thrown if the
incoming request has:
* no body
* no content-type header
In this case, a null value is returned.
Issue: SPR-13147
Includes a revision for consistent and defensive Servlet 3.0 method calls across Spring's web abstraction (in particular, also working in debug mode where method references may get resolved early, so ternary expressions are to be avoided).
Issue: SPR-13420
This commit improves the documentation in the reference manual for the
HtmlUnit & Selenium WebDriver integration in the Spring MVC Test
framework by mentioning the group and artifact IDs required for this
functionality.

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".
Issue: SPR-13345
Prior to this commit, ServletWebRequest would call
HttpServletResponse.getStatus(), which is a Servlet 3.x method.
This commit checks if this method is available before calling it, thus
keeping Servlet 2.5 compatibility.
Issue: SPR-13396
Related to that, HibernateTransactionManager specifically checks for active physical connections on reset as of Hibernate 5.
