What is java generic? Do you mean that you don't know or are you =
hand waving?
Does RPG compiled to jvm bytecodes have the same functionality as the =
native RPG? There are reasons that the jvm can not do well. It has =
limited data types and lacks support for constructs not in the java =
language.

Not really, and actually there's no reason it couldn't as I've seen an =

compiler that spit out Java vm bytecode -- just nobody sees a need for =

different tasks and both do fairly well what they were designed for.

Agreed, but Java has the environment and C++ doesn't, and doesn't =
lend
itself to that kind of environment either.
