With this commit the Spring Expression Language now supports
increment (++) and decrement (--) operators. These can be
used as either prefix or postfix operators. For example:
'somearray[index++]' and 'somearray[--index]' are valid.
In order to support this there are serious changes to the
evaluation process for expressions. The concept of a
value reference for an expression component has been introduced.
Value references can be passed around and at any time the actual
value can be retrieved (via a get) or set (where applicable). This
was needed to avoid double evaluation of expression components.
For example, in evaluating the expression 'somearray[index++]--'
without a value reference SpEL would need to evaluate the
'somearray[index++]' component twice, once to get the value and
then again to determine where to put the new value. If that
component is evaluated twice, index would be double incremented.
A value reference for 'somearray[index++]' avoids this problem.
Many new tests have been introduced into the EvaluationTests
to ensure not only that ++ and -- work but also that the
introduction of value references across the all of SpEL has
not caused regressions.

When obtaining an async result, tests will now await concurrent
processing to complete for the exact amount of time equal to the
actual async timeout value.

Before this change View implementations set the response content type
to the fixed value they were configured with.
This change makes it possible to configure a View implementation with
a more general media type, e.g. "application/*+xml", and then set the
response type to the more specific requested media type, e.g.
"application/vnd.example-v1+xml".

Some servlet containers (iPlanet) parse the Accept header and return
multiple values from request.getHeader("Accept"). The HttpHeaders
getAccept method has been updated to accommodate that hopefully
without causing any other issues.
The extra functionality is in effect only if we find only one
MediaType and there is more than one value for the 'Accept' header.

Previously UriComponentsBuilder used a regular expression for parsing
query name-value pairs where both name and value were expected to not
contain neither '&', not '='. The idea is that the presence of reserved
characters makes it impossible to guess correctly how to parse the
query string (e.g. a=b&c).
This change relaxes the constraint on query param values, allowing them
to contain '='. In effect '&' is the ultimate separator of name-value
pairs, and any '=' in values is ignored. For example "q=1USD=?EUR" is
interpreted as "q equals '1USD=?EUR'".

Prior to this commit, utility methods in JdbcTestUtils interpreted SQL
comments as separate statements, resulting in an exception when such a
script is executed.
This commit addresses this issue by introducing a
readScript(lineNumberReader, String) method that accepts a comment
prefix. Comment lines are therefore no longer returned in the parsed
script. Furthermore, the existing readScript(lineNumberReader) method
now delegates to this new readScript() method, supplying "--" as the
default comment prefix.

SpringRunnerContextCacheTests suffers from JDK7-related non-determinism
in values returned from Class#getDeclaredMethods(), which in turn
affects JUnit and its execution of @Test methods.
This commit addresses this issue by introducing an
OrderedMethodsSpringJUnit4ClassRunner that sorts the test methods
alphabetically, which is actually required for
SpringRunnerContextCacheTests to work properly.

This commit introduces RequestAndSessionScopedBeansWacTests which
verifies support for request and session scoped beans in the Spring
TestContext Framework (TCF).
This support was actually introduced as an intentional side effect of
the work performed for SPR-5243 through the addition of the new
WebTestExecutionListener.

Reverted change for @Bean methods that declare FactoryBean as their return type: The effects of trying to create the FactoryBean to find out about its implementation type are too far-reaching. It's better to recommend declaring a specific return type in the method signature if you want the container to specifically react to your implementation type.
Issue: SPR-9857
Includes a change for factory methods that declare their return type as FactoryBean: When asked for a specific type match (e.g. LoadTimeWeaverAware), we do check early singleton instances as well (reusing the instances that we create for getObjectType checks). This is necessary in order to make @Bean method introspection as capable as XML bean definition introspection, even in case of the @Bean method using a generic FactoryBean declaration for its return type (instead of the FactoryBean impl class).

* SPR-9284:
Allow MapToMap conversion to work when the target map does not have a default constructor (as long as a new map copy is not required).
Polish trailing whitespace
Update the ReflectiveMethodResolver and ReflectivePropertyAccessor
to allow methods and properties of java.lang.Class to be resolved
when the target object is a class.

Refactor ConfigurationClassEnhancer to allow cglib caching of
generated classes. Prior to this commit each enhanced @Configuration
class would consume permgen space when created.
The CallbackFilter and Callback Types are now defined as static final
members so that they can be shared by all enhancers. Only the
callbackInstances remain specific to a @Configuration class and
these are not used by cglib as part of the cache key.

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.
