The target parameters for a FlashMap must be decoded to be able to
match them to the parameters of incoming requests given that the
HttpServletRequest returns decoded request parameters.

This change ensures that when the Accept and the Producible media types
are equally specific, we use the one from the Accept header, which may
for example carry a different charset.
Caching of resovled exceptions introduced in SPR-7703 also introduced a
side effect whereby if exactly one exception was previously cached, any
other exception would appear as a match to the previously matched
@ExceptionHandler method.
This change ensures use of a fresh map when determining matching
@ExceptionHandler methods while also updating the cache.
Issue: SPR-9209
The "includes" and "isCompatibleWith" methods of MediaType take into
account media types with suffices (e.g. application/soap+xml) including
wildcards with suffices (e.g. application/*+xml). However before this
change, the isWildcardSubtype() method returned true only for subtype
"*". Now a media type such as application/*+xml is also recognized as
having a wildcard subtype.

Usually this request attribute is set for all sub-classes of
AbstractUrlHandlerMapping and therefore whenever
AnnotationMethodHandlerAdapter is used. However, having a
default value to fall back on in AnnotationMethodHandlerAdapter
is still appropriate in general and also considering the Javadoc
of HandlerMapping.INTROSPECT_TYPE_LEVEL_MAPPING.

Changes introduced in Spring 3.1 for Environment support inadvertently
established a cyclic dependency between the
org.springframework.web.context and
org.springframework.web.context.support packages, specifically through
web.context.ContextLoader's invocation of
web.context.support.WebApplicationContextUtils#initServletPropertySources.
This commit introduces ConfigurableWebEnvironment to break this cyclic
dependency. All web.context.ConfigurableWebApplicationContext types now
return web.context.ConfigurableWebEnvironment from their #getEnvironment
methods; web.context.support.StandardServletEnvironment now implements
ConfigurableWebEnvironment and makes the call to
web.context.support.WebApplicationContextUtils#initServletPropertySources
within its implementation of #initPropertySources. This means that
web.context.ContextLoader now invokes
web.context.ConfigurableWebEnvironment#initPropertySources instead of
web.context.support.WebApplicationContextUtils#initServletPropertySources
and thus the cycle is broken.

Prior to this change, AbstractApplicationContext#setParent replaced the
child context's Environment with the parent's Environment if available.
This has the negative effect of potentially changing the type of the
child context's Environment, and in any case causes property sources
added directly against the child environment to be ignored. This
situation could easily occur if a WebApplicationContext child had a
non-web ApplicationContext set as its parent. In this case the parent
Environment type would (likely) be StandardEnvironment, while the child
Environment type would (likely) be StandardServletEnvironment. By
directly inheriting the parent environment, critical property sources
such as ServletContextPropertySource are lost entirely.
This commit introduces the concept of merging an environment through
the new ConfigurableEnvironment#merge method. Instead of replacing the
child's environment with the parent's,
AbstractApplicationContext#setParent now merges property sources as
well as active and default profile names from the parent into the
child. In this way, distinct environment objects are maintained with
specific types and property sources preserved. See #merge Javadoc for
additional details.

As of Spring 3.1 URI variables can be used for data binding purposes in
addition to request parameters (including query string and form params)
In some cases URI variables and request params can overlap (e.g. form
contains a child entity with an entityId as hidden form input while the
URI contains the entityId of the parent entity) and that can lead to
surprises if the application already exists.
This change ensures that request parameters are used first and URI
vars are added only if they don't overlap. Ideally however an
application should not use the same uri variable name as the name of
a request parameter where they don't refer to the same value.

Jackson 2 uses completely new package names and new maven artifact ids.
This change adds Jackson 2 as an optional dependency and also provides
MappingJackson2HttpMessageConverter and MappingJackson2JsonView for use
with the new version.
The MVC namespace and the MVC Java config detect and use
MappingJackson2HttpMessageConverter if Jackson 2 is present.
Otherwise if Jackson 1.x is present,
then MappingJacksonHttpMessageConverter is used.

This was supported in DefaultAnnotationHandlerMapping but not in the
RequestMappingHandlerMapping. The specific scenario where this matters
is a controller decorated with a JDK proxy. In this scenario the
HandlerMapping looks at interfaces only to decide if the bean is a
controller. The @Controller annotation is better left (and required)
on the class.

Invalid Content-Type or Accept header values previously resulted in the
IllegalArgumentException getting propagated. After this change such

Ensure that both FlashMapManager methods - the one invoked at the
start of a request and the one invoked before a redirect, update
the underlying storage fully since it's not guaranteed that both
will be invoked on any given request.
Also move the logic to remove expired FlashMap instances to the
metohd invoked at the start of a request to ensure the check is
made frequently enough.

Prior to this commit, StandardServletEnvironment's servlet context
PropertySource remained stubbed out until it the ServletContext became
available and could be replaced during the refresh() of its enclosing
WebApplicationContext. This behavior is acceptable in most cases.
However, if the user has declared an ApplicationContextInitializer that
attempts to access servlet context-params via the Environment API, this
result in a kind of 'false negative', i.e. the context-param key and
value are actually present in the ServletContext, but the PropertySource
representing servlet context params is still a stub at this point,
meaning that it returns an empty result in all cases.
With this change, WebApplicationContextUtils#initServletPropertySources
is invoked eagerly by the ContextLoader if any ACI classes have been
declared. This swaps out the servlet context property source stub for
the real thing just in time for ACIs to use it if necessary.
Extra guard logic has been added to #initServletPropertySources to
ensure idempotency -- once the stub has been replaced, the method
never attempts the replacement again, e.g. during the normal context
refresh() when this method will be called again.
Issue: SPR-8991
- Perform early check whether any ACI classes have been declared and
exit immediately if not, avoiding any other processing

Issue: SPR-8991
The "default" FlashMapManager implementation added in 3.1 was invoked
after the redirect, which is too late in cases where the HTTP session
has not been yet been created since as the response is committed.
This change corrects the issue and makes other improvements to the
FlashMapManager implementation such as extracting a base
AbstractFlashMapManager class and making it easier for other
implementations to be added (for example cookie-based).
A direct path match with incorrect HTTP request method was causing another
request mapping with a pattern and a correct HTTP method to be ignored.
The bug affects the new @MVC support classes
(i.e. RequestMappingHandlerMapping).
It should be possible to progress from extending
WebMvcConfigurerAdapter (w/ @EnableWebMvc) to extending
WebMvcConfigurationSupport directly, to extending
DelegatingWebMvcConfigurationSupport. This change
makes that possible.
