Review Request: Zero JNI handles fix

[Gary Benson]

Hi all,

Zero will exit with an error when invoked with -Xcheck:jni.
This webrev fixes:

  http://cr.openjdk.java.net/~gbenson/zero-jnihandles-fix/

Note that this is actually a pretty old issue, but the fix
for it got lost from the IcedTea repositories.  There's more
information here:

  http://icedtea.classpath.org/bugzilla/show_bug.cgi?id=323

I don't have a bug id for this.

Cheers,
Gary
