I will defer to your judgment that having any kind of Sun JRE is
better than an IBM JRE, from a selling point of view.
From a technical perspective, we agree that eventually you will need a
high-performance JRE. I see a couple of paths:
- Port/write a JIT for the Sun JRE for z architecture. A

Well, not just mine. Part of IBM's investigation into participating in the
OpenSolaris project was whether the IBM JDK

Well, it's a start. It gets us A Java, and there are enough religious

implementation that if you're trying to

Give us a little time, OK? Neale's only had a week or so to get this far.

David,

IBM has made a huge investment in JIT technology for z architecture
(z/OS and Linux) in their SDK. It would be much better IMO if IBM
offered a Solaris z port of their SDK. After all, if IBM isn't
interested in Solaris z

In a memory constrained environment a JIT is frequently a lose. There are
in fact lots of cases where straight interpreting is better. It is also
