public class PortNameProblem
extends Entity

Illustrates a problem with port naming and cloning.

In this actor, the Java variable of the port is named "poorlyNamedInput" but the constructor uses "input", which is the wrong name. This used to result in a NullPointerException. Now, we test for this in Entity.clone().
