This particular point may be misleading for a newbie. Paul, in general, Java exceptions can be handled using RPG's normal exception handling. For example
monitor;
someJavaMethod();
on-error;
...
endmon;

The RuntimeException is one subclass of Java Exception that apparently causes the JVM to become unusable. D*B, just a guess, but maybe those exceptions would normally be indications that something has gone wrong with the JVM, so Java ends the JVM. For example, it's impossible within Java to have a null instance ("this") within a method when the method is called from Java, but it's possible when the method is called using JNI.
