This should be significantly faster than our standard algorithm, for a very common case. Motivated by SPR-9802, even if the fix there uses a different approach, with transaction name determination not calling getMostSpecificMethod at all anymore.
Issue: SPR-9802
As of Spring 3.0.4, we were trying to expose the target method signature as transaction name. Unfortunately, the algorithm called the ClassUtils.getMostSpecificMethod helper method which performs a quite expensive reflective search. As of this commit, we're simply concatenating the target class name with the method name, accepting the use of the concrete target class (which is arguably more meaningful for monitoring anyway) even when the method implementation actually sits on a base class.

These features require Java 6 or higher due to their dependency on the ResourceBundle.Control class. To some degree, ResourceBundleMessageSource catches up with ReloadableResourceBundleMessageSource now. However, as noted in the javadoc, there are still severe limitations in the standard ResourceBundle class that justify an ongoing investment in our own ReloadableResourceBundleMessageSource (based on the Spring resource abstraction, with manual parsing of properties files).

Before this change the PathExtensionContentNegotiationStrategy accessed
the ServletContext via request.getServletContext, which is Servlet 3
specific. To work around it, there is now a Servlet-specific sub-class
that accepts a ServletContext as a constructor argument.
The ContentNegotiationManagerFactoryBean is now ServletContextAware and
if it has a ServletContext it creates the Servlet-specific sub-class
of PathExtensionContentNegotiationStrategy.
The ContentNegotiationManagerFactoryBean is now also used in several
places internally -- MVC namespace, MVC Java config, and the
ContentNegotiatingViewResolver -- to reduce duplication.

Before this commit, UriComponentsBuilder did not handle opaque URIs at
all. After this commit it does.
Support is introduced by making UriComponents an abstract base class,
and having two concrete subclasses: HierarchicalUriComponents and
OpaqueUriComponents. The former is more or less the same as the old
UriComponents class.

This new converter uses StringHttpMessageConverter internally combined
with a ConversionService for converting String content to and from the
target object type.

Autowired methods might have been skipped on subsequent creation of further bean instances due to the 'skip' flag set to false outside of the synchronized block, with another thread entering the block and setting the flag to true in the meantime.
Issue: SPR-9806
LiveBeansView includes MBean exposure as well as Servlet exposure, with JSON as the initial output format. In order to identify an MBean per application, a new "getApplicationName()" method got introduced on the ApplicationContext interface, returning the Servlet container context path in case of a web application and defaulting to the empty String. MBean exposure can be driven by the "spring.liveBeansView.mbeanDomain" property, e.g. specifying "liveBeansView" as its value, leading to "liveBeansView:application=" or "liveBeansView:application=/myapp" style names for the per-application MBean.

The RequestMethodsRequestCondition is now protected against HTTP
request method values not present in the RequestMethod enumeration
(e.g. PROPFIND).
Issue: SPR-9815
This change introduces two new interceptors with callback methods
for concurrent request handling. These interfaces are
CallableProcessingInterceptor and DeferredResultProcessingInterceptor.
Unlike a HandlerInterceptor, and its AsyncHandlerInterceptor sub-type,
which intercepts the invocation of a handler in he main request
processing thread, the two new interfaces are aimed at intercepting the
asynchronous execution of a Callable or a DeferredResult.
This allows for the registration of thread initialization logic in the
case of Callable executed with an AsyncTaskExecutor, or for centralized
tracking of the completion and/or expiration of a DeferredResult.
Prior to this commit, JibxMarshaller used a SAX ContentHandler to
marshal to StAX XMLEventWriters, which inadvertently resulted in the
deletion of XML comments.
After this commit, JibxMarshaller adapts the XMLEventWriter into an
XMLStreamWriter and comments are preserved.
Issue: SPR-9768
Prior to this change, @ComponentScan required the declaration of
exactly one of the #value, #basePackage or #basePackageClasses
attributes in order to determine which package(s) to scan.
This commit introduces support for base package inference, relaxing the
above requirement and falling back to scanning the package in which the
@ComponentScan-annotated class is declared.

Float parameter handling appears to be marginally more expensive under
JDK7, with the testGetFloatParameterWithDefaultValueHandlingIsFastEnough
test clocking in anywhere from 250 to 315 ms. This violates the current
test threshold of 250 ms, so this commit ups the timeout value to 350 ms
with the assumption that this is indeed a marginal and therefore overall
negligible performance degradation.
String#substring has become significantly slower as of JDK 1.7.0_06 [1],
such that there are performance degradations by a factor of 100-1000 in
ResourceDatabasePopulator, especially for large SQL files.
This commit works around this problem by minimizing the substring scope
to the least amount possible to prevent unnecessary internal copying of
strings (which seems to cause the issue).

Issue: SPR-9781
Class#getDeclaredMembers returns arbitrary results under JDK7. This
results in non-deterministic execution of JUnit test methods, often
revealing unintended dependencies between methods that rely on a
specific order to succeed.
JUnit 4.11 contains support for predictable test ordering [1], but at
the time of this commit, JUnit 4.11 has not yet been released.
Therefore we are testing against a snapshot version [2], which has been
uploaded to repo.springsource.org [3] for easy access. Note that this
artifact may be removed when JUnit 4.11 goes GA.
- Care has been taken to ensure that spring-test's compile-time
dependency on JUnit remains at 4.10. This means that the spring-test
pom.xml will continue to have an optional <dependency> on JUnit
4.10, instead of the 4.11 snapshot.
- For reasons not fully understood, the upgrade to the 4.11 snapshot
of junit-dep caused NoSuchMethodErrors around certain Hamcrest
types, particularly CoreMatchers and Matchers. import statements
have been updated accordingly throughout affected test cases.
- Runtime errors also occurred around uses of JUnit @Rule and
ExpectedException. These have been reverted to use simpler
mechanisms like @Test(expected) in the meantime.
- Some test methods with order-based dependencies on one another have
been renamed in order to fall in line with JUnit 4.11's new method
ordering (as opposed to actually fixing the inter-test
dependencies). In other areas, the fix was as simple as adding a
tearDown method and cleaning up state.
- For no apparent reason, the timeout in AspectJAutoProxyCreatorTests'
testAspectsAndAdvisorNotAppliedToPrototypeIsFastEnough method begins
to be exceeded. Prior to this commit the timeout value was 3000 ms;
on the CI server under Linux/JDK6 and JDK7, the test begins taking
anywhere from 3500-5500 ms with this commit. It is presumed that
this is an incidental artifact of the upgrade to JUnit 4.11. In any
case, there are no changes to src/main in this commit, so this
should not actually represent a performance risk for Spring
Framework users. The timeout has been increased to 6000 ms to
accommodate this situation.

- Allow reset of GlobalAdvisorAdapterRegistry
Provide a reset() method allowing the GlobalAdvisorAdapterRegistry
instance to be replaced with a fresh instance. This method has
primarily been added to allow unit tests to leave the registry
in a known state.
- Protect against the fact that calls to configuration class methods
my occur in a random order.

- Increase max heap size in gradle wrapper.
- Use MockProperties implementation to protect against security
exceptions.
- Replace windows CRLF with LF in various tests.
- Increase Thread.sleep times to account for lack of precision on
Windows.
