Mojarra 2.2 versions diverging

Question

https://javaserverfaces.java.net/nonav/2.2/releasenotes.html lists two diverging version branches of JSF2.2 where, strangely, 2.2.8-xx seems to be more recent than 2.2.9 and above.

Some bugs are fixed only in 2.2.9 (https://github.com/javaserverfaces/mojarra/issues/3384), some only in 2.2.8-xx (https://github.com/javaserverfaces/mojarra/issues/4111) and some in both versions (https://github.com/javaserverfaces/mojarra/issues/3133).

Whats the reason behind this and which branch should I use in production? Both seem to contain important bugfixes.

I could not find anything about this with google. Maybe the mojarra guys could add some information to the release notes.

Answer 1

Mojarra 2.2.8-xx releases are built specifically for Oracle WebLogic 12c with handpicked bugfixes from newer releases backported every time. WebLogic has namely a bug in its integrated Weld version which made it incompatible with Mojarra 2.2.9 and newer where the fix for issue 3345 was introduced.

If you aren't using WebLogic 12c, then just ignore the 2.2.8-xx releases altogether and pick the newest 2.2.x which is as of today 2.2.14. If you're however using WebLogic 12c, then you should actually focus on obtaining a maintenance pack from Oracle WebLogic support. It'll bundle the newer Mojarra 2.2.8-xx version.
