RE: Problem with using JNI to start JVM from rpgle

I have a program that I put together a while back (with the great help of 
Barbara Morris) that uses JNI apis to start JVM. I was passing JNI_VERSION_1_2. 
Everything was working OK, but since the latest java stuff is installed on the 
ISeries box, I started getting "IllegalArgumentException:key can't be empty" 
when trying to list system properties in Java pgms. Having investigated, I 
figured out that QJVAJNI service pgm has changed and a new version of JNI 
(JNI_VERSION_1_4) was available. When I tried to pass JNI_VERSION_1_4 
everything worked fine. But I need to find a way for this pgm to work on any 
JNI level. Basically I can not always pass 1_4. Is there any way to determine 
what JNI version is installed on an ISeries?
Thanks for any help in advance.
