handleConnect got unexpected exception, maybe return null statusCode and statusPhase, that client mistaken connected

[wsky]

} catch (LinkException e) {
            ack.statusCode = e.getErrorCode();
            ack.statusPhase = e.getMessage();
            this.logger.warn(Text.E_REFUSE, e);
        }

if e from this:

try {
            this.internalTopService.checkSign(headers);
        } catch (Exception e2) {
            throw new LinkException(e2.getMessage(), e2);
        }

if e2 was java.lang.NullPointerException, message was null, so both errorCode and message passed to client were null

same as internalOnMessage

private void internalOnMessage(ChannelContext context, Message msg, Identity msgFrom) throws LinkException {
        if (msg.messageType == MessageType.SENDACK) {
            this.endpoint.getMessageHandler().onMessage(msg.content, msgFrom);
            return;
        }

        EndpointContext endpointContext = new EndpointContext(
                context, this.endpoint, msgFrom, msg.flag, msg.token);
        endpointContext.setMessage(msg.content);
        try {
            this.endpoint.getMessageHandler().onMessage(endpointContext);
        } catch (Exception e) {
            // onMessage error should be reply to client
            if (e instanceof LinkException)
                endpointContext.error(
                        ((LinkException) e).getErrorCode(),
                        ((LinkException) e).getMessage());
            else
                endpointContext.error(0, e.getMessage());
        }
    }
