Hi Joshua,<div><br></div><div>If you can get a running 32bit system, I'd suggest you do so, as you'll get up to speed right away. I can't test VMKit on a 64bits machine, and I have been aware that there are some compilation/execution problems. Besides, the current GCs of VMKit do not work on 64bits (neither MMTk nor GCMmap2).</div>

</div>Regarding to j3 in 64 bit version, it should work now after we've<br>
found crush reason,<br>
both in Debug and in Release versions. (and its 32 bit version was<br>
continuously working)<br>
<br>
But your case is something strange, crush didn't type such messages.<br>
Have you taken VMkit from svn and latest version?<br>
Also, to get j3 running recompile classpath with<br>
-fno-omit-frame-pointer (or take my patch from here:<br>
<a href="http://lists.cs.uiuc.edu/pipermail/vmkit-commits/attachments/20100719/35754a6f/attachment.bin" target="_blank">http://lists.cs.uiuc.edu/pipermail/vmkit-commits/attachments/20100719/35754a6f/attachment.bin</a><br>
and apply it:<br>
$ cd classpath-0.97.2<br>
$ patch ./configure ./classpath_configure64.patch<br>
)<br>
<br>
That's now on j3<br>
<br>
Regards,<br>
