The Java EE 6 specifications were released in December 2009, together with Glassfish v3, the first "production-quality release" of a Java EE 6 server. "Marketing release" would have been more appropriate, since going by the number of bugs in Glassfish 3.0, the main driving factor for the release date was quite obviously not a quality benchmark, but simply the need for Sun as the Java EE champion to release a working server simultaneously with the specifications.
