Cannot set minimum size for NewtCanvasAWT

I noticed that no matter what value I put for minimum size of NewtCanvasAWT, it keeps reverting back to current size. After debugging I notices this is the reason why:

https://github.com/sgothel/jogl/blob/master/src/newt/classes/com/jogamp/newt/awt/NewtCanvasAWT.java#L408

    private final void updateLayoutSize() {
        final Window w = newtChild;
        if( null != w ) {
            // use NEWT child's size for min/pref size!
            final java.awt.Dimension minSize = new java.awt.Dimension(w.getWidth(), w.getHeight());
            setMinimumSize(minSize);
            setPreferredSize(minSize);
        }
    }

Why is it necessary for NewtCanvasAWT to keep updating its own size? Is this a bug?
If not then what is the proper way of setting the minimum size of NewtCanvasAWT?

Actually, there is no notion of minimum size in NEWT as far as I know, maybe Sven can confirm.

If you set the size of your attached GLWindow then the NewtCanvasAWT will use the same size as its minimum size.

As a workaround I can force the minimum size by keep resetting it in the resize event function. And it works so I know NEWT is capable of it. But the workaround is ugly so someone just needs to delete the calls to setMinimumSize() in that updateLayoutSize() method and I think it will work nicely.

I tried the following but it didn't work. Looks like GLWindow size keeps getting recalculated.

canvas.getNEWTChild().setSize(100, 100);
