Starting another JVM from RPG

    When we want to run Java from RPG, we typically use the getJniEnv method to 
start up the JVM. The second run is faster since getJniEnv retreives the 
existing JVM that was already started. The problem is what to do if there are 
two different Java applications that use mutually exclusive classpaths. The 
first Java program is run in a new JVM that was started up by getJniEnv with 
the correct classpath. When RPG attempts to run the second Java program on the 
existing JVM (which now has the 'wrong'  classpath) it bombs on a classNotFound 
error. If startJVM was used instead of getJniEnv, the JVM would be recreated 
each time the second Java program runs- this would ruin performance. Is there a 
way to create two JVMs- each only once, and then retrieve the correct one for a 
particular Java program?
