36 * The class XIOProblem is a wrapper class for Java IOExceptions. It is thrown when errors 
37 * occur during the serialisation of ATObjects to Packets (and the inverse), to schedule 
38 * messages for transmission to another actor. Another class that raises these exceptions 
39 * is NATNamespace to report that it failed to read in a particular file to lazily load a
40 * library.
