Long method names are overflowing their containers, and the relationship edges aren't obeying the specified ports on the tail end. It looks like their X position is correct, but the y possition is not. I'd prefer it to look <a href="http://www.cs.colorado.edu/~kena/classes/6448/f08/_Media/homework1-2.png" rel="nofollow noreferrer">something like this</a> where both the subclass relationship arrows are combined to form a single connection with the bottom center point in the superclass container. If I remove the port specifications, the edges no longer clip into the nodes they connect, but the layout is still not what I'd consider ideal.</p> <p><img src="https://i.stack.imgur.com/gbuUq.png" alt="Without explicit port specifications"></p>
