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

[roger riggs]

Hi Kumar,

The parameter names are purely local to the macro. They do not need to 
be unique.
If the macro was longer (though it is now a lot longer than the original),
it might make the code more readable.
(Though I'm sure someone has a different convention).
