java: indicate reads writes illusory patience socketchannel around object(in|out)putstreams?

i combined an objectinputsteam objectoutputstream patience socketchannel am perplexing review concurrently. formula something this:

socketchannel = socketchannel.open(destnode);
objectoutputstream = new objectoutputstream(channels.newoutputstream(socketchannel));
objectinputstream = new objectinputstream(channels.newinputstream(socketchannel));

thread replythread = new thread("sendrunnable-replythread") {
    @override
    open vacant run() {
        try {
            byte respond = objectinputstream.readbyte();//(a)
            //..process reply
        } locate (throwable e) {
            logger.warn("problem reading accept reply.", e);
        }
    }
};
replythread.start();

objectoutputstream.writeobject(someobject);//(b)
//..more writing

problem during line (b) blocks until review during line (a) completes (blocks vigilant returned selectablechannel#blockinglock() ). nonetheless app explanation dictates review finish until writes complete, have an effective deadlock.

socketchannel javadocs contend indicate reads writes supported.

i means such problem i attempted unchanging dale solution:

socket dale = new socket();
socket.connect(destnode);
final outputstream outputstream = socket.getoutputstream();
objectoutputstream = new objectoutputstream(outputstream);
objectinputstream = new objectinputstream(socket.getinputstream());

however, following i can't take advantage opening advantages filechannel#transferto(...)
