I don't work for Sun so I can't speak for them.  The last I heard was that
Sun was looking at GPLv3, and considering its use for one or more projects,
either dual licensed with the CDDL, or on its own.

My own personal opinion is that dual licensing should be avoided because
it makes things needlessly complicated, and there is also the real danger
of license-based forks being introduced.

The short answer is: seek professional legal council.  The longer answer,
bearing in mind that IANAL, is that yes, a clean room implementation
would be legal.
