    [JSPF-115] Fix NPE that causes hang
    
    This NPE happens when a PortUnreachableException (that doesn't have a
    message) is received in the exceptionally block, but other exceptions
    without a message also can trigger this bug. Also added the null check
    for e.getCause(), just in case.
