This fix really just lets the
catch (KeeperException.NodeExistsException e)
clause catch exceptions thrown in theif (createParentsIfNeeded)
clause. Previously, since the twocatch
statements were for the same try, theKeeperException.NodeExistsException
logic would not be called if that error was thrown when creating the node after creating the parents. This case can easily be seen when trying to call create.orSetData() in parallel on the same node, while creating parents if needed. This is because theNoNodeException
would be thrown for both parallel calls, but only one would be able to create the new node in the catch statement, and the other would get an un-catchableNodeExistsException
.
