Class loading may cause loading of some other system/internal classes (for example loading of java.util.concurrent classes when an other thread loads some classes concurrently). The fix updates ClassPrepare test so it skip events for "unexpected" classes. Also it adds a testcase to verify that classes which are explicitly loaded on other thread do not generate ClassPrepare event on the test thread.
