Description

Attempting to copy a node to the location of an existing node fails with a PathNotFoundException, generated by the call to session.getItem() at line 136 of AbstractMoveCopyOperation.java. The attached script demonstrates the failure.

By introducing a breakpoint in CopyOperation.java's copy(Node src, Node dstParent, String name) anywhere after the replacement node is created (line 109), I've been able to make requests succeed. It seems as though there must be a race or a caching issue there.
