    Problems with defining node types in clustered environment

    Rick Cole Newbie

      We are having a problem running Modeshape in a clustered environment. The issue arises when we attempt to define custom node types (via a .cnd file) in our .json repository configuration file. The first instance of Modeshape comes up fine. The problem is when the second instance comes up. We get a stack trace containing an NPE on both instances. When we remove the reference to the .cnd file from the repository .json file, everything starts up properly.

      This may to be related to MODE-1703, which appears to have been fixed back about 24 days ago, but we are still seeing a problem . Any help on this would be greatly appreciated.

      Here is the stack trace we are seeing on the first server we started:
