Informed by

a Gooogle alert bot I found the "Project Guest VM" a open source project under Sun(http://research.sun.com/projects/). Looking at the project page http://kenai.com/projects/guestvm and checking some of the source files, it shows up that there are JNode code in it, infact the JNodeFS sources. Is this something we should act on? They attached their own license on top of ours. I guess that's a standard procedure they use on all their source files. Their license is GPL2.0, and they say the made some changes to our code, so shouldn't they post back the changes or should we download the sources and merge the things we like?

Interesting

... so shouldn't they post back the changes

AFAIK they are not obliged to post their changes to us. But you can read the LGPL license to figure this out.

... or should we download the sources and merge the things we like?

That would be the best approach.

Changes they made so far

You can see the changes they made to the fs code here:
- https://kenai.com/hg/guestvm~guestvm/rev/907484119ee2 which is an interesting off by one (could probably be quicly reviewed and commited to jnode)
- https://kenai.com/hg/guestvm~guestvm/rev/cc1fac2d20c6 a more complexe change which needs more review it has to do with adding rename/delete support to ext3
