Not true.  It doesn&#x27;t matter who owns the copyright, because Sun has the keys to the kingdom and can publish a revision to the CDDL whenever they want.  Forward compatibility is not something you opt-in to with the CDDL (unlike you have to do with the GPL).<p>This is, for example, how Mozilla has been relicensed to MPL 2.0 from earlier versions of the license—which the CDDL is based on, incidentally—even though there are no &quot;any later version&quot; notices anywhere in the headers or other files.
