BlueCove stack ShutDown Completed automatically

[Manish Kumar Singh]

I am using BlueCove for communicating between Android and windows devices.
I am able to establish connection for first time . However, after
receiving data from android device (sending acknowledgement to android)
"BlueCove stack ShutDown" occurs. I want server (ie on Windows Devices) to
remain in listening mode .
My code :

StreamConnectionNotifier streamConnNotifier =
(StreamConnectionNotifier)Connector.open( connectionString );

//Wait for client connection
System.out.println("\nServer Started. Waiting for clients to
connect...");
StreamConnection connection=streamConnNotifier.acceptAndOpen();

RemoteDevice dev = RemoteDevice.getRemoteDevice(connection);
System.out.println("Remote device address:
"+dev.getBluetoothAddress());
System.out.println("Remote device name:
"+dev.getFriendlyName(true));


InputStream inStream=connection.openInputStream();
BufferedReader bReader=new BufferedReader(new
InputStreamReader(inStream));
String lineRead=bReader.readLine();
System.out.println(lineRead);


OutputStream outStream=connection.openOutputStream();
/* BufferedWriter bWriter=new BufferedWriter(new
OutputStreamWriter(outStream));
bWriter.write("Response String from SPP Server\r\n");*/

PrintWriter pWriter=new PrintWriter(new
OutputStreamWriter(outStream));
pWriter.write("Response String from SPP Server\r\n");
pWriter.flush();
pWriter.close();

streamConnNotifier.close();


Evenafter i am commenting "streamConnNotifier.close(); " BlueCove stack
ShutDown still occurs . Please Help
