Please don't take the the following as representing an answer from Red
Hat. With that qualification out of the way, I can say that am
personally very interested in contributing to a Java-on-Java OpenJDK
runtime -- having experienced many of the benefits of such a model
working on the JikesRVM and Xerox Interlisp-D runtimes.

This idea has many benefits, as you mentioned. I think it is
particularly valuable that a Java-on-Java implementation replaces the
hard, black box that currently separates VM tech from JDK tech with a
much more fluid, transparent boundary layer. The more that those who use
the JVM can understand about what it does for them and at what cost the
better.

So, this gets a very excited thumbs up from me!

regards,


Andrew Dinn
