Deprecate HttpStatus.MOVED_TEMPORARILY

Deprecate HttpStatus.MOVED_TEMPORARILY in favor of HttpStatus.FOUND
since HttpStatus.valueOf(302) will always return FOUND.

The name of the 302 status code was changed between HTTP 1.0 and
HTTP 1.1 but the underlying meaning remains the same.

StringToEnumConverterFactory class from enum value

Update StringToEnumConverterFactory to search superclasses until
Class.isEnum() returns true. This allows conversion when the
enum class is obtained from the enum value:

    public static enum SubFoo {
        BAR { String s() { return "x"; } };
        abstract String s();
    }

    conversionService.convert("BAR", SubFoo.BAR.getClass())

This fix is particularly important when converting collections of
enums.

MergePlugin uses project source not jar source

Update gradle MergePlugin to use the 'project.sourceSets.main.output'
for jar content rather than 'project.jar.source'. This prevents
superfluous MANIFEST.MF files from appearing in the merged jar.

Clean up console output for spring-beans tests
Update Eclipse import organization rules

The following changes have been made to the JDT UI prefs to conform to
existing conventions throughout the codebase:

 - always favor .* syntax for static imports
 - always list static imports last

Re-run `gradle eclipse` and refresh projects within Eclipse to make
this change take effect.
Re-enable ignored SecurityManager-related test

Prior to this change, CallbacksSecurityTests#testContainerPrivileges was
@Ignored because it caused the build to fail under Gradle. After some
analysis, the root cause was determined to be the fact that (a) a
restrictive SecurityManager is active during the running of this test,
and (b), Gradle intercepts System.out and routes it through its internal
LogBack-based logging system. LogBack requires a call to
Class#getClassLoader when handling logging statements, and the
SecurityManager disallows this call, thus raising the error that fails
the build.

This commit solves the problem by eliminating the System.out.println
call in question and removing the @Ignore annotation from the test. The
console output was diagnostic in nature anyway, and not required for the
successful execution of the test's assertions.

Re-enable JaxWsSupportTests

These tests still fail under Eclipse for unknown reasons, but do work
under Gradle, so are thus re-enabled by removing the @Ignore.

Improve diagnostics for invalid testGroup values
Update AbstractMBeanServerTests hierarchy to JUnit 4

This commit lays the groundwork for introducing TestGroup#JMXMP and
related assumptions in select JMX-related tests in a subsequent commit;
JUnit assumptions require JUnit 4+ to function properly, so the entire
AbstractMBeanServerTests hierarchy must be moved over to JUnit 4+ style.
