Major Description
Calling Workspace#copy for referenceable nodes (or child nodes) fails with ConstraintViolationException which IMHO is caused by not generating a new UUID:
javax.jcr.nodetype.ConstraintViolationException: org.apache.jackrabbit.oak.api.CommitFailedException: OakConstraint0030: Uniqueness constraint violated for key 9a68f118-af82-43c2-a0df-d4178d7bd198
