Please re-review.
I missed a warning that the CHECK_NULL macros was being redefined.
Retaining the previous changes to java/util/jar/pack that removed the
redefinition
addresses the issue.
The webrev now only has a few small changes to cleanup the name and use
of CHECK macros.
The CHECK_NULL_* macros are more generally useful without the JNU_ prefix.
The JNU_CHECK_EXCEPTION* macros apply only when there is an jni environment.
