Multi-Tasking Virtual Machine (Project Barcelona)

[Matt Ficken]

yeah, java 5 is really old. I agree any new mvm related project should be
based on java 6 or 7.

I'm not a lawyer, but it sounds like section IIID of the JRL allows for
mixing parts of JRL licensed code with 'open source licenses', so I think I
should be able to start a sourceforge project(I like the AGPL license) to
adapt the mvm code to java 7. Am I misunderstanding the JRL?
