Actually, it clouds the picture again.  ( but that is good. maybe I will end
up understanding Java better )

Yesterday, I asked the question:

and Hans responded:

Which lead me immediately to upgrade my opinion of Java and start the
process of asking why RPG is not made to compile down to Java bytecode.
What I am interested in is mixing Java and RPG  without the need of a
cumbersome interface barrier.  That is why microsoft's CLI has my attention.
In my windows C++ code I can mix in C# and VB.NET classes without much
hassle.

So what prevents the RPG compiler from translating RPG to Java ByteCodes?
Esp if VisualAge RPG possibly does.  The thinking being that if RPG can
translate to ByteCodes, then the programmer can also natively reference Java
classes contained in the Java ByteCode stream emitted by the compiling of
Java code.
