JRE crash in Java serial app with JSSC in W10 enviroment


I'm new to Java and when trying to run the following code with jssc-2.8.0 library, at the "serialPort.openPort()" method the IntelliJ IDE crashes and reports:

A fatal error has been detected by the Java Runtime Environment:

EXCEPTION_ACCESS_VIOLATION (0xc0000005) at pc=0x000000007110b5db, pid=11596, tid=5204

No core dump will be written. Minidumps are not enabled by default on client versions of Windows

If you would like to submit a bug report, please visit: https://bugreport.java.com/bugreport/crash.jsp The crash happened outside the Java Virtual Machine in native code. See problematic frame for where to report the bug.

Source code follows:

import jssc.*;

public class Main {

    public static void main(String[] args) {

        // Pass port number thru argument
        String port = args[0];

        SerialPort serialPort = new SerialPort(port);
        try {
            System.out.println("Opening port " + port + " ...");

            serialPort.setFlowControlMode(SerialPort.FLOWCONTROL_RTSCTS_IN | SerialPort.FLOWCONTROL_RTSCTS_OUT);

            serialPort.writeString("COM3 opened !!!");

            PortReader portReader = new PortReader(serialPort);

            serialPort.addEventListener(portReader, SerialPort.MASK_RXCHAR);

        } catch (Exception e) {
            System.out.println("There are an error on writing string to port т: " + e);

import jssc.*;

public class PortReader implements SerialPortEventListener {
    SerialPort serialPort;
    public PortReader(SerialPort serialPort) {
        this.serialPort = serialPort;

    public void serialEvent(SerialPortEvent event) {
        if (event.isRXCHAR() && event.getEventValue() > 0) {
            try {
                String receivedData = serialPort.readString(event.getEventValue());
                System.out.println("Received response: " + receivedData);
            } catch (SerialPortException ex) {
                System.out.println("Error in receiving string from COM-port: " + ex);
