RFR: (8031737) rename jni_util.h macros for checking and returning on exceptions

[Kumar Srinivasan]

Hi Roger,

Its confusing to use a JNU_ prefixed macro on a method not involvng jni,
why not rename these to modulo JNU_ ?

I am cc'ing Alex as he has a related bug fix in his queue for pack's jni 
code.
