I recently attended a talk by a Sun engineer, Charlie Hunt, regarding performance. The talk was interesting enough but one question was regarding the release date of 1.7.
He said it's delayed as there are parties who are refusing to sign off JSRs they own and thus preventing the 1.7 release. It apparently has something to do with the cost of determining your Sun compliance.
What is the full story or a pointer in the right direction?
What triggered my question was the amazing long release notes for 6u18 .
