RFR for JDK-7027502: Test failures in demo/jvmti/hprof testcases, need to be othervm

[Tristan Yan]

Hi All
Please help to review the code change for JDK-7027502.

http://cr.openjdk.java.net/~tyan/JDK-7027502/

Description:
This test was failed in JPRT test but recently we test with same 
binaries run, it doesn't fail any more. The intention for this code 
change is bringing this test back to normal test and make this test 
robust and more informative.  Change includes
1. Remove this test from ProblemList.
2. Change static member total_turns_taken into a local variable.

Please let me know your comment on this.
Thank you.
Tristan
