Hi all,

could you please review this small fix for b6969574 test? 

the tests compares performance of different invocation modes, long time ago it started to report that MH.invokeWithArguments() is slower than Method.invoke(). 8078511[1] was filed to consider possible improvement for invokeWithArguments. however, since MH.invokeWithArguments performance isn't expected to  be better thanMethod.invoke, it was decided to remove it from the test.

Thanks,
