Right.

What if you use someone else's coolio tool that happens to use Java, and
then you try to run your RPGMail?  That first classpath wouldn't include
your directories - adding your directories to the CLASSPATH envvar
wouldn't make any difference because the JVM would have already been
started with the first classpath.

On V5R1, especially if you're doing development, you might not notice
this problem, because all the ILE compilers run in *NEW.  When the
compile ends, the *NEW actgrp ends, which causes the JVM to end.  When
you call your Java-using program again, you get a new JVM.  On V5R2,
this doesn't happen any more.
