Description

When calling TelnetClient#disconnect(), a NullPointerException is thrown because
either __input or __output is already null. After fixing my working copy of the
source, an additional NPE is thrown in SocketClient#disconnect() because the
socket variable is already null. I've patched both files to check for null of
the affected intasnce variables before calling the close() methods and will be
submitting a patch.
