RFR 8208303: Track JNI failures and fail tests

[JC Beyler]

Hi all,

The tests in the HeapMonitor subsystem has a lot of JNI calls. There is a
need for verification and testing if anything in the JNI subsystem failed
unexpectedly.

Here is a webrev that tracks if a JNI call does fail and the tests will
fail if any JNI call does fail.

Could I have a few reviews please for:
Webrev: http://cr.openjdk.java.net/~jcbeyler/8208303/webrev.00/
Bug: https://bugs.openjdk.java.net/browse/JDK-8208303

Thanks,
Jc
