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

[Ulf Zibis]

Hi,

thanks, I thought this is an endless loop until the inner condition is fulfilled, not really noting, 
that 0==false (one more reason to use true/false instead 1/0, IMHO).

Can you explain the trick, why you use a one-time-loop instead of a single statement?

-Ulf
