> Following test case reproduces the bug:
>     public void test_read_$ByteBufferII_Blocking() throws IOException {
>         final int CAPACITY_NORMAL = 200;
>         SocketChannel sc = SocketChannel.open();
>         ServerSocket server = new ServerSocket(50000);
>         byte[] data = new byte[CAPACITY_NORMAL];
>         for (int i = 0; i < CAPACITY_NORMAL; i++) {
>             data[i] = (byte) i;
>         }
>         ByteBuffer[] bufferArray = new ByteBuffer[2];
>         bufferArray[0] = ByteBuffer.allocate(CAPACITY_NORMAL);
>         bufferArray[1] = ByteBuffer.allocate(CAPACITY_NORMAL);
>         sc.connect(new InetSocketAddress(InetAddress.getLocalHost(),50000));
>         Socket socket = server.accept();
>         OutputStream out = socket.getOutputStream();
>         out.write(data);
>         // Harmony fails to return here.
>         sc.read(bufferArray);
>     }
> RI returns while Harmony hangs.
