[11u] RFR 8261262: Kitchensink24HStress.java crashed with EXCEPTION_ACCESS_VIOLATION

[Zhengyu Gu]

I would like to backport this patch to 11u for parity with Oracle 
11.0.12-oracle.

The original bug: https://bugs.openjdk.java.net/browse/JDK-8261262
The original patch: https://github.com/openjdk/jdk/commit/7b9d2562

The original patch does not apply cleanly. 11u still uses VM operation 
for getting current location, while the original patch uses handshake 
(via. JDK 8242427)


11u webrev: http://cr.openjdk.java.net/~zgu/JDK-8261262-11u/webrev.00/

Test:
   vmTestbase_nsk_jvmti

Thanks,
