So intention for this code change is bringing this test back;  add some debug info and try to avoid possible issues in this test. I agree this code change won't solve the failure happened. But this test was put into ProblemList two years ago better move for this is move out it from ProblemList and trace down the issue in our normal nightly.

So better output + removing from the exclude list seems fine here. (cc'ing serviceability-dev as that is actually the mailing list for the HPROF and JVM TI areas).

I'm not sure what is actually being proposed. I don't really see 
anything that would help diagnoze the original issue. But bring back the 
test - maybe this was a bug elsewhere that has now been fixed.
