35 * Instances of XClassNotFound are raised when the AmbientTalk interpreter's attempt to load a
36 * class failed. This occurs either when using the <tt>jlobby</tt> construct to explicitly load
37 * a class, but it may also occur during the deserialisation of a {@link Packet}, when the 
38 * contents of that Packet contained an unknown class.
