Yesterday the GlassFish team gave an overview of their roadmap to let the community know about the plans for GlassFish since the Oracle takeover.  Importantly, they cleared up all the FUD around the impacts of the acquisition, clearly stating that Oracle are committed to the community, and that there is no changes to how the GlassFish project operates.

While retaining the open source edition of GlassFish, there will be an Oracle GlassFish Server distribution supported by Oracle, with evaluation and production licences. Closed Source Add Ons will be bundled along with the Oracle distribution.
