Hi Mark,

      Brian and I have been discussing this mostly on the
jikesrvm-researchers list.  (You may want to check the thread in the
archive.)

We very much want to contribution the changes.  We are about to get IBM's
approval to do this.  Brian recently mentioned the FSF licensing statement
requirement.   I'll have to get our legal folks involved again to deal with
the issues.

Mike

Thanks. Nice to know this is working.

I found this code at
http://www-124.ibm.com/developerworks/oss/cvs/jikesrvm/rvm/src/vm/GNUClasspathSupport/


If you have comments on the current Classpath VM interface please let us
know. Were there things that are missing or could be made easier?

In the future I hope to move things like Thread.java and Runtime.java
out of the VM interfaces and just have small VMThread and VMRuntime stub
classes. This is what was recently done for Throwable but I see that you
don't use the VMThrowable. Was anything missing from the VMThrowable
Interface or was it just easier for you to keep your own Throwable
implementation?

Would you mind submitting these changes to GNU Classpath? (Brian can
probably help with any copyright assignment or licensing issues.) Or
describe the changes that you needed to make? Are they online somewhere?

Thanks,

Mark
