Problems with Quasar and Java Agent

[PhilipH]

Hi:

Firstly, thank you for the amazing Quasar project.  I've been using it for an AI project and it has been incredibly useful.

I'm having a problem with a recent upgrade to Java 11. I'm using NetBeans 9.0 and Maven on Windows 10.  I put together a very simple HelloWorld app to illustrate my problem. 

package com.acellan.kibihee.quasarhelloworld;

import co.paralleluniverse.fibers.Fiber;

/**

 */

public class QuasarTest {

    public QuasarTest() {

        // default        

    }

    public static void main(String[] args) {

        QuasarTest qt = new QuasarTest();

        qt.test();

    }

    public void test() {

        new Fiber<Void>(() -> {

            System.out.println("Hello! I'm a Quasar Fiber!");

        }).start();

    }

}

... with the following POM:

...and when I run in debug, here's what I get:

...etc....

Any idea what I'm doing wrong?

Many thanks
