SocketManagerHandler - Exiting on IOE ServerSocketManagerHa

[hero]

After receiving and reading a BytesMessage correctly I get the following error after finishing MessageHandler:

Someone has closed the connection (either server or client)
or somebody has done Thread.interrupt() on the UIL2 thread
(which amounts to the same thing).
