Michael, Otto is using the RPG support that wrappers the JNI.  The RPG
compiler/runtime handles calling GetObjectArrayElement and copying the
Java array into the RPG array, setting any unpassed elements to null. 
Since RPG doesn't have variable-dimension arrays, the RPG program can't
get at the actual number of elements in the Java array.  (Although it
_is_ possible for RPG programmers to do the JNI calls directly.)
