1、 return (ByteBuffer) buffers.get().clear();
（2）the "get()" function make the "writeBuffers" do "initialValue",to get a new DirectByteBuffer

private final ThreadLocal<ByteBuffer> writeBuffers = new ThreadLocal<ByteBuffer>() {
    @Override
    protected ByteBuffer initialValue() {
        return ByteBuffer.allocateDirect(INITIAL_BUFFER_SIZE);
    }
};

2、I want to know. Will ‘DirectByteBuffer’ be released clean

I have solve it.It is because I create too many threads.
