I created an enhancement request at https://jogamp.org/bugzilla/show_bug.cgi?id=1303. You can register your email address on it as a CC to get notified of changes.

I can't see any reason why this wasn't included in the original release, since clRetainMemObject() has been around since OpenCL 1.0. Maybe the original author just didn't think of it :)
