Class ExceptionUtil

public class ExceptionUtil
extends Object

This class handles the different interruption classes. It can be: - InterruptedException - InterruptedIOException (inherits IOException); used in IO - ClosedByInterruptException (inherits IOException) , - SocketTimeoutException inherits InterruptedIOException but is not a real interruption, so we have to distinguish the case. This pattern is unfortunately common.
