Maybe that detail is what makes you think this bug is related to Bug 1198. Sure .. that is the current behavior of AWT (not us), and there is nothing we can do about it. However, the deadlock shall be avoided despite this behavior. (In reply to Xerxes Rånby from comment #5) > The NPE seen in Comment 2 and Comment 3 indicate that awtConfig is null in > JAWTWindow This alone promotes this bug report for 2.3.2, since it is quite sloppy to use a filed in JAWTWindow w/ unusable state. JAWTWindow itself is essential. And yes, we have to triage this issue in more detail and setup constrains about awtConfig field. http://jogamp.org/log/irc/jogamp_20151006050515.html#l349 20151006 21:39:53 <sgothel> my suggestion: if set to null other than invalidate -> exception 20151006 21:40:11 <sgothel> then at lock .. if null -> exception 20151006 21:40:20 <sgothel> then we need to fix that NEWT.AWT driver 20151006 21:40:43 <sgothel> i.e. going the constraint way .. properly defining awtConfig lifecycle 20151006 21:41:00 <sgothel> as you mentioned: it shall not be null branch ready to merge: if set to null other than invalidate -> exception https://github.com/xranby/jogl/commits/Bug1247 With this change we replace the NPE with the new exception: >> GearsES2 0x53bd815b, angle 0.0, [l -1.33125, r 1.33125, b -1.0, t

JAWTWindow fail early w/ useful info: setAWTGraphicsConfiguration(..)

commit c1594efa78951f187a75ec0b9a85cf64fba418d4
TestGearsNewtAWTWrapper fails AWT recreation case removeNotify -> addNotify,
e.g. by moving to other monitor
AWTCanvas removeNotify didn't cause 'local' destruction of the NEWT window,
allowing a 'recreate' w/ subsequent addNotify.
This case has been hacked-into NEWT.AWT.WindowDriver + AWTCanvas:
- suppression of window destroy events
- keeping fields/states intact in NEWT.AWT.WindowDriver
- propagating signals appropriately
Note: This is barely a working hack and not a fine piece of software :)
This AWT backend driver exists only due to historical reasons.
This hack simply proves that JAWTWindow works properly.
