Please provide a brief summary of the bug

I am trying to run to get response from serial port.
I have checked all the possible outcomes to fix this issue but I am unable to fix it.
Below is the error im getting again and again.

Please provide steps to reproduce where possible

import gnu.io.CommPortIdentifier;
import gnu.io.CommPort;
import gnu.io.SerialPort;
import java.io.InputStream;
import java.io.OutputStream;
import java.util.Scanner;

public class CommPortExample {
public static void main(String args[])
{
Scanner scanner = new Scanner(System.in);
System.out.println("Enter command: ");
String command = scanner.nextLine();
scanner.close();
String portName = "COM11";

    try{
        CommPortIdentifier portIdentifier = CommPortIdentifier.getPortIdentifier(portName);
        if (portIdentifier.isCurrentlyOwned())
        {
            System.out.println("Port is currently in use");
        }
        else {
            CommPort commPort = portIdentifier.open(CommPortExample.class.getName(), 2000);

            if (commPort instanceof SerialPort){
                SerialPort sP =(SerialPort)commPort;
                sP.setSerialPortParams(9600, SerialPort.DATABITS_8, SerialPort.STOPBITS_1, SerialPort.PARITY_NONE);

                InputStream in = sP.getInputStream();
                OutputStream out = sP.getOutputStream();

                out.write(command.getBytes());

                byte[] buffer = new byte[1024];
                int len;

                StringBuilder response = new StringBuilder();
                while ((len=in.read(buffer)) >-1 )
            {
               response.append(new String(buffer, 0,len));
               if (response.toString().contains("Expected response"))
               {
                break;
               }
            }
            System.out.println("System Response: "+response.toString());
            sP.close();

            }

            else
            {
                System.out.println("Error");

            }
        }
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

}

Expected Results

Enter command:
O0265Z

The device connected to usb port will beep after getting this command

Actual Results

Enter command:
O0265Z

@itoobaykhan That's a crash in the native code in the rxtxSerial.dll library. You'll need to report this issue to that library.

Oh okay. Thank you. I'll report it.
