This is the error

Comment 1 Sven Gothel 2014-03-10 18:21:36 CET
This is not an error, but a notification
that you have not closed the display / device properly.

The display is kept open, since you don't close the window,
here the GLWindow bound to the NewtCanvasAWT.
Comment 2 Giuseppe Barbieri 2014-03-10 18:29:06 CET
How do I close the windows? destroy() on the glWindow doesn't work either
