This class is intended to catch Early EOF errors that occur when the client disconnects while the server is reading from the input stream. We catch the org.ecplise.jetty.io.EofException rather than the more generic java.io.EOFException to ensure that we're only catching jetty server based errors where the client disconnects, as specified by EofException. /**
