Please review this fix for JDK-8251904.  The fix ignores ClassNotFoundExceptions that are thrown when calling Class.forName() because they can be caused by OutOfMemoryErrors.  These can get thrown because of other threads calling GarbageUtils.eatMemory().

The test was run 1000 times on Linux x64 without the fix and failed once.  It was run 5000 times with the fix and had no failures.  The change was also tested by running Mach5 tier5 on Windows and Linux.

Thanks, Harold
