Bug Description

When using my pwf account to start JHelioviewer application over "ssh -X" hangs with no possibility to close it on the splash screen with "Starting OpenGL". It can be reproduced just by starting any time and happens in trunk and the Andre's release branch.

The Log on the console is:

Looks like an uncatched exception, when no OpenGL is available. Should be easily fixable by catching the exception.

One thing we might try, before actually catching the exception, is to activate the debug options provided by the OpenGL java library "JOGL".

java -Dnewt.debug=all -Dnativewindow.debug=all -Djogl.debug=true -jar JHelioviewer.jar

Perhaps this output would be nice to see for Markus, too.

Fix in the experimental-release branch: Fallback to software mode when exception is thrown during the initialization of OpenGL

Okay, maybe interesting is that connecting to one server its working fine (okay, not super fast over the wifi down here), while connecting to the other server does not work, while in both cases my local X Server to which its connecting is the same.

I attach a detailed log.

Thanks for the log. This looks really strange - they seem to do some hacks in the JOGL libraries, that do not work in all (including this) cases.

I posted a thread over here to see what to do in the long run. I think for now, catching the exception is the best option.
