No, you'd have to rewrite the part of the core class library that
communicates with the VM. I don't think it would be practical.

Sure. How much do you know about GCC internals?

You always have to have a JRE. Maybe it's in a shared library, like
libgcj. I guess I don't know why you want to do this.

Let's get real. I could do move GCJ to use the OpenJDK libraries in
maybe six months to a year. I am better qualified than almost anyone
else to do it. I'm not sure there is anything much someone can do in
two months, unless it's simply adding a few classes or bringing some
classes up to date.

GCJ hasn't been worked on for some time. Will anyone work on it again?
I don't know. It's very out of date.
Andrew.
