Hi Mark, Any ideas when you want 5.5.0.Final out of the way? I believe the initial problems with 5.5.0.CR1 are now resolved (protobuf\jBPM issue, class not found issue). We still have a Guvnor issue (when starting up without an existing repository there's a JCR related error, but Jervis is looking into this - after he's done with 5.3.1. BZs). With kind regards, Mike
