NodeNotFoundInParentException is thrown when unlocking a node within a transaction

Lock and unlock a node in transactional environment. E.g. in a container with default transaction management and attribute types or within an explicitly defined transaction: @Test public void shouldLockUnlockWithinTransaction() throws Exception { final String path = "/test" ; Node parent = session.getRootNode().addNode( "test" ); parent.addMixin( "mix:lockable" ); session.save(); startTransaction(); LockManager lockMgr = session.getWorkspace().getLockManager(); lockMgr.lock(path, true , true , Long .MAX_VALUE, session.getUserID()); lockMgr.unlock(path); commitTransaction(); }
