Code review request: 8002273 NMT to report JNI memory leaks when -Xcheck:jni is on

[Karen Kinnear]

Zhengyu,

Looks good and thank you for checking that with -Xcheck:jni.

I checked the documentation, and the -Xcheck:jni documentation includes examples, it is not intended to ensure
that we document every detailed check that we made, so it appears that we don't need to add documentation here.

thanks,
Karen
