Hi Thomas, Thank you for the rapid reply. We cannot reproduce the problem starting a node with an empty repository. The problem only appears when:
- Cluster Node 1 is started against an empty repository and creates a workspace, registering custom namespaces and nodetypes (Cluster Node 1 starts up without issue) - Cluster Node 2 is started up without a copy of the custom namespace and nodetype definitions in its own FileSystem (Cluster Node 2 fails to start up) It looks like issue JCR-1558 matches the problem I'm having exactly. Is there any work planned on that particular issue? I ask because the custom namespaces and nodetypes are something we can't realistically get away from, as we are using Brix, which makes use of these.
