I am very excited to say that Eclipse GlassFish 5.1-RC1 is now released! The version we are working on, Eclipse GlassFish 5.1.0, will be Java EE 8 certified once it is fully released, however, the RC1 gives the community an opportunity to test the code and provide their feedback. We are making available nightly builds as well.

Huge progress has been made in the Jakarta EE world over the last couple of months. A big thank you to everyone involved!

Let’s recap all the successes and take a moment to celebrate our little victories!

GlassFish and Oracle Java EE API contributions to Jakarta EE are now complete.

Java EE TCKs are open sourced and hosted at the Eclipse Foundation.

Nightly builds for Eclipse GlassFish are available on the Foundation’s Jenkins-based Common Build Infrastructure here.

The work on ensuring that Eclipse GlassFish is Java EE 8 compatible and can be branded as Java EE 8 compatible is well on its way. A test infrastructure at the Eclipse Foundation is now ready for testing Eclipse GlassFish against the Java EE 8 TCKs. The Eclipse Foundation has signed the Oracle Java EE TCK agreement, which will allow us to proceed with the testing.



We expect that Eclipse GlassFish sources will become the basis for an implementation of the Jakarta EE specifications.
