8211291: Backout JDK-8210842 Handle JNIGlobalRefLocker.cpp

[Mikael Vidstedt]

Backout of JDK-8210842 since it seems to cause some build issues on Windows and Solaris:

bug: https://bugs.openjdk.java.net/browse/JDK-8211291
webrev:  http://cr.openjdk.java.net/~mikael/webrevs/8211291/webrev.00/open/webrev/ <http://cr.openjdk.java.net/~mikael/webrevs/8211291/webrev.00/open/webrev/>

Produced using:

hg backout -r 2712735bc434

Running a job to make sure it resolves the build issues.

Cheers,
Mikael
