This commit introduces a test in XmlBeanFactoryTests that verifies that
CGLIB generated subclasses for method injected beans are reused across
bean factories for identical bean definitions. In other words, by
verifying that the same CGLIB generated class is reused for identical
bean definitions, we can be certain that Spring is no longer generating
identical, duplicate classes that consume memory in the VM.

- Consistent importing of org.junit.Assert.*;
- Proper declaration of expected exceptions via @test(expected).
- Renamed SpEL ExpressionTestCase to AbstractExpressionTests.
- Formatting and test method naming conventions.

Prior to this commit several test classes named "*Test" were not
recognized as tests by the Gradle build. This is due to the configured
inclusion of '**/*Tests.*' which follows Spring's naming convention for
test classes.

This commit addresses this issue by:

 - Renaming real test classes consistently to "*Tests".
 - Renaming internal test classes to "*TestCase".
 - Renaming @WebTest to @WebTestStereotype.
 - Disabling broken tests in AnnoDrivenStaticEntityMockingControlTest.
 - Modifying the Gradle build configuration so that classes ending in
   either "*Tests" or "*Test" are considered test classes.

Issue: SPR-11384

Also avoided unnecessary substring creation for field error access with wildcard.

Issue: SPR-11374

Stereotype annotations should support a 'value' attribute for
specifying the name of the Spring-managed component; however,
@RestController currently does not provide such an attribute.

This commit introduces a 'value' attribute in @RestController so that
developers can provide custom names for components annotated with
@RestController.

This turned out to be a bug in the ASM-based AnnotationMetadata implementation where has/getAnnotatedMethods didn't consider meta-annotations., in contrast to its StandardAnnotationMetadata sibling.

This allows scoped proxy definitions to override regular application bean definitions (again).

Issue: SPR-11229

Prevent early FactoryBean creation for type checking purposes when coming from a factory method on yet another bean (e.g. from a configuration class)

Specifically, if the current factory has Qualifier/ContextAnnotationAutowireCandidateResolver set up, it is important to pass it on to ancestor factories to get consistent qualifier matching results.

Issue: SPR-10966

Fixed inner bean name determination for multi-level nesting scenario, calculating a unique bean name as early as possible now (and for any kind of bean scope)

Our per-bean caching in AutowiredAnnotationBeanPostProcessor and co relies on unique bean names, so this change fixes potential cache mismatch problems occuring there.

Attempt to fix performance build by scanning for a free JMX port.

Issue: SPR-10561

Extended testPrototypeCreationWithOverriddenAutowiredPropertiesIsFastEnough's deadline (since that test repeatedly failed on the CI server)

Fix CacheAspectSupport to consider a cache hit from any of the multiple
@Cachables that may have been specified using the @Caching annotation.

Prior to this commit the following scenario would never produce a hit:

	@Caching(cacheable = {
		@Cacheable(value = "c1", unless = "#result.size() < 4"),
		@Cacheable(value = "c2", unless = "#result.size() > 3")
	})

Issue: SPR-11124

Update code to have a consistent number of new-line characters after
import statements.

Apply consistent styling to new classes introduced in Spring 4.0.

- Javadoc line wrapping, whitespace and formatting
- General code whitespace
- Consistent Assert.notNull messages

Delete the unused GlassFishLoadTimeWeaverTests and in the process
fix the "Unable to load JUnit4 runner to calculate Ignored test cases"
Gradle error.

Issue: SPR-10563

Fix remaining Java compiler warnings, mainly around missing
generics or deprecated code.

Also add the `-Werror` compiler option to ensure that any future
warnings will fail the build.

 - Cache interceptor internals now operate on collections of
   <? extends Cache> instead of <Cache>.
 - Deleted unused imports.
 - Deleted dead code.
 - Suppressed warnings for resource leaks related to not closing
   ApplicationContexts in tests.
 - Suppressed further non-issue warnings in tests.
