Hi all,

could you please review this small fix?
since jit-tester tests can be generated by another version of JDK, there is probability that some of exception messages or stack trace have been changed. this can cause lots of false positive test results. in order to avoid that and make tests more robust, I have changed JIT tester to print/compare just only exception class names.

Thanks,
