[classlib][nio] java.nio.channels.SocketChannel.read(ByteBuffer[],int,int) fails to return
even there are some data available.
------------------------------------------------------------------------------------------------------------------------------

         Key: HARMONY-728
         URL: http://issues.apache.org/jira/browse/HARMONY-728
     Project: Harmony
        Type: Bug

  Components: Classlib  
    Reporter: Andrew Zhang


java.nio.channels.SocketChannel.read(ByteBuffer[],int,int) fails to return even there are
some data available.

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.
