I am getting a lot of these, javax.jcr.nodetype.ConstraintViolationException: OakConstraint0030: Uniqueness constraint violated for key 42cd9011-84a8-485f-b723-435439ddcc71
It seems to happen on session.save(), having just created a node of type nt:unstructured, with a mixing node type which inherits mix:referenceable. I can't seem to see any other pattern. Is there anything in particular that could cause this, with code that worked ok with jackrabbit 2.8? This is with oak 1.0.3, but I've seen it on 1.0.1 and 1.0.2 as well. -- -Tor
