OpenEJB 3.0 Final is released

The OpenEJB developer team has completed the official OpenEJB 3.0 final release, which is their first major release since early January 2008. Congratulations to the developers and to the Apache Software Foundation!

After no small amount of pain, I became comfortable with the idea of increasing the similarity of the tests.
