when activeMQ server is Linux, this problem will still happen.

I try to fix it like this: class StompClient Line 142:

                do {
                    ch = in.read();
                    if(ch<0){
                        onCriticalError(new IOException("stome server disconnected!"));
                        return;
                    }
                } while (ch < 'A' || ch > 'Z');

By @conanca comment (0ct 19,2012) context : Linux with activeMQ still have SocketException at line class StompClient Line 144 (ch=in.read()) when executing the test class => Exception occurs when client.disconnect(); is invoked in test class. (Line 130) then I fixed it by modifying StompClient Line 142 as

        // skip lead trash
        do { 
            try {
                ch = in.read();
            } catch (SocketException e) {
                if (!running) { // exception to ignore
                    break;
                } else {
                    throw e;// normal exception
                }
            }
            if (ch < 0){
                            onCriticalError(new IOException("stome server disconnected!"));
                            return;
            }
        } while (ch < 'A' || ch > 'Z');
        if (!running) break;
        // read frame
        (...)

=> ignore exception when SocketException is thrown at in.read() and the reader should be stopped (running == false)
