This change involves a modification of the "writeContent" template method to include the "jsonPrefix" String instead of the "prefixJson" boolean flag. Since said template method has only been introduced in 3.2.2, this change should hopefully not be a problem.

Previously ConfigurationClassParser could override a nested
@Configuration without consideration of @Bean's defined in parent
classes.
This commit ensures that if the original ConfigurationClass contains
additional bean definitions it is processed again.

(cherry picked from commit 940011e)
Commit 5b1165 was an attempt to leave semicolon content in the URL path
while ignoring it for request mapping purposes. However, it becomes
quite difficult to manage and semicolon content should not always be
ignored (sometimes a semicolon is used as a separator of multiple items
in a path segment, rather than for matrix variables).
This change effectively reverts back to the original approach in 3.2
where a flag on AbstractHandlerMapping can be used to have semicolon
content removed or kept. If kept, path segments with matrix variables
must be represented with a path segment.
The main difference is that by default it is removed everywhere
including the MVC namespace and Java config.

Previously DeferredResult locked around the setting of the result
including handling up to the part of submitting a dispatch. This
can cause a deadlock if a timeout occurs at the same time since
the Tomcat timeout thread has its own locking that permits only
one thread to do timeout or dispatch processing.
The fix reduces the locking to cover only the attempt to set the
DeferredResult but not the dispatching.

This change should be the final piece in the puzzle to let SmartInstantiationAwareBeanPostProcessor's predictBeanType predict a FactoryBean-produced type, effectively as a semantic alternative to its postProcessBeforeInstantiation-related role.

Spring 3.2.2 introduced a change to avoid closing the response stream
in HttpMessageConverters (SPR-10095). However, the InputStream of
resources being written, for example as part of a multi-part request
should be closed. This change ensures that.
Issue: SPR-10460
If type conversion turns an empty request parameter value (i.e. "") to
null, we should treat it as a missing value. By default the
ConversionService doesn't change empty strings and therefore one must
explicitly convert them to null for example by registering a
StringTrimmerEditor with emptyAsNull=true.

A recent change in FormTag to prepend the context and servlet paths if
not present, causes issues when used in portlet applications.
This change introduces a servletRelativeAction form tag attribute that
must be used for the context and servlet paths to be prepended.
Issue: SPR-10382
Previously ContentNegotiationManager continued with the next
ContentNegotiationStrategy only if the current one returned an empty
list. Now it also does that if the current ContentNegotiationStrategy
returns "*/*". Since the absence of an Accept header and "*/*" have
the same meaning, this allows a default content type to be used in
either case.

@InitBinder and @ModelAttribute methods in @ControllerAdvice classes
are now invoked first, allowing any such methods in the @Controller
class to override them.
Issue: SPR-10419
Refactor ConfigurationClassEnhancer so that BeanFactory instances are
not held against CGLIB Callback objects. Enhanced @Configuration classes
now use the BeanFactoryAware interface in order to obtain a BeanFactory.
This change has the additional benefit that a static final field can
now be used to hold all Callback instances.
Issue: SPR-10307
Change ContextHierarchyDirtiesContextTests to obtain beans whilst the
ApplicationContext is still open, rather than trying to obtain them
after the context has been closed.
Introduce new @Conditional annotation that can be used to filter
which @Configuration classes or methods are loaded. @Conditional
can be used directly or as a meta-annotation. Condition implementations
are provided via the 'Condition' interface and are free to filter based
on any criteria available at the time that they run. The
ConditionalContext provides access to the BeanDefinitionRegistry,
Environment and ConfigurableListableBeanFactory along with a
ResourceLoader and ClassLoader.
The existing @Profile annotation has been refactored as a @Conditional
with the added benefit that it can now be used as a method level
annotation.
Update AnnotationMetadata and MethodMetadata to extend from a new
AnnotatedTypeMetadata base interface containing the methods that are
common to both. Also introduce new getAllAnnotationAttributes methods
providing MultiValueMap access to both annotation and meta-annotation
attributes.
Existing classreading and standard implementations have been
refactored to support the new interface.
Add PropertySourcesPlaceholderConfigurer.getAppliedPropertySources() to
allow access to the PropertySources that were actually applied.
Issue: SPR-10545
Update ServletContextAwareProcessor to allow subclasses to support late
binding of the ServletConfig and/or ServletContext. Allows for the
post-processor to be registered before the servlet environment has been
initialized.
