Thank you for the explanation about HPJ.

I think that the original question that started this thread was whether or  not 
there were
 any plans to have something like HPJ for z/os java In the future.
Now it turns out that it was already here but gone for whatever reasons that 
led IBM to discontinue it.

High Performance Java (HPJ) was not simply a CICS facility. It was a
compiler which produced machine-executable code (load module) instead of
Java interpretable bytecodes (class file). It was discontinued, for a number
of reasons, when Java 1.2 was released.
