Hi,

I'm trying to perform a rolling upgrade of Hotrod Server from 5.1.1.FINAL to 5.1.2.FINAL. Unfortunately, I get an exception:

Failed to boot JBoss:

I'm curious whether it is possible at all? Has anyone managed to join 5.1.2 node to 5.1.1 cluster?

I've added configuration file and two log files from running and joining node.
