Mike,

Actually most of the IBM'ers I have heard speak about this issue say that
the JIT compiler is the direction of the future.  It already produces code
that is comparable to optimization level 40 and will only get better.
Application servers like WebSphere and Tomcat are unable to take advantage
of the output of CRTJVAPGM so a JIT became necessary.  Much to the
surprise of the members of the VM team that thought static compilation
would be the best result, the JIT produces amazing results.  This is due
to a lot of incredible patented technologies that IBM has developed in
their research labs.

I use the JIT exclusively on a V4R5 system with great results and it is
supposed to be much much faster at V5R1 and V5R2.

I suspect that CRTJVAPGM will be phased out in future releases unless they
can come up with some ways to make it relevant again.  It doesn't really
make sense to waste engineering effort on it, however, when a JIT can
produce such great results.
