Is it possible to create an OpenGL, GLCanvas() element on MacOS X 10.15 (Java)?

Question

I am currently attempting to update a program that utilizes OpenGL. I need to get the program to work on MacOS X 10.15. I am using JDK SE 14 and the most recent version of JOGL found at https://jogamp.org/. The issue I run into is when the program tries to create a GLCanvas() or GLJPanel(), it will instantly crash. Below is the snippet of code that causes the crash.

public void initFrame(){
    
    JFrame frame = new JFrame();
    frame.setDefaultCloseOperation(JFrame.DO_NOTHING_ON_CLOSE);

    JRootPane root = frame.getRootPane( );   // make small title bar
    root.putClientProperty( "Window.style", "small" );
    
   GLCanvas canvas = new GLCanvas();

    frame.setUndecorated(undecorated);
    canvas.addGLEventListener(this);
    canvas.addMouseListener(this);
    canvas.addMouseMotionListener(this);
    

    frame.setSize(frameWidth, frameHeight);
    frame.setLocation(frameX,frameY);

    frame.add(canvas);

    GraphicsEnvironment env = GraphicsEnvironment.getLocalGraphicsEnvironment();
    GraphicsDevice device = env.getDefaultScreenDevice();

    FPSAnimator animator = new FPSAnimator(canvas,33);  

    frame.setVisible(true);
    
    animator.start();
}

The following error is produced when the code reaches GLCanvas canvas = new GLCanvas()

I am not sure how to interpret this error, and was wondering if there were any workarounds to getting GLCanvas() to work on MacOS X 10.15. I plan to switch the entire application to Metal in the coming months, but I need a quick fix for an upcoming project.
