Well, as I understand CDDL isn't compatible with GPL. so if you're pulling it into MediaWiki at runtime you enter the GPL Mystery Zone(TM) where things may, or may not, be properly licensed. :)
But I wouldn't object to CDDL code being in the repository, as long as we're not mixing the files together.
Thanks. I've asked the developer if Sun is willing to relicense the code. If not, I'll add as CDDL, and ensure I don't mix code/files.
V/r,
