Mojarra 1.2_09 BETA1 is now available. For full details, you can read the release notes , but the coolest thing in this release, I think, is the introduction of Groovy support. For more information, you can read about it on Ryan's blog here: http://blogs.sun.com/rlubke/entry/groovy_mojarra
That's all new code, so we could use people hammering at that before the final stamp is put on this release. Note also, that this is the implementation of the MR2 version of the spec, for those that are following that.
