Remove the use of TestNG from java/lang/annotation tests. Interesting that JUnit scans annotations on member classes, so we can't put malformed annotations on classes nested in the test class; we can put them on package-private classes in the same source file instead. Also refactored LoaderLeakTest to perform GC more reliably within our test framework.
