class MyGLEvenListener extends GLEvenListener {

  static boolean once = false;

  public void init(GLAutoDrawable drawable) {
    GL2ES2 gl2es2;

      once = true;
      GL gl = drawable.getGL();

You also can enable 'JVM wide' DebugGL by simply setting property 'jogl.debug.DebugGL':
  -Djogl.debug.DebugGL
This will also enable the native debug context, see below.

(Same goes for TraceGL*)

If you like to use the native debug context as well
you would need to issue:

GLContext ctx = ...; // not yet natively created by 1st makeCurrent()
ctx.setContextCreationFlags(GLContext.CTX_OPTION_DEBUG);

.. or:

GLWindow glWin = ... ; // newly create one, not yet visible
glWin.setContextCreationFlags(GLContext.CTX_OPTION_DEBUG);
