Hi foks
I've been using jogl for a couple of weeks and I've been hugely impressed with how clean the api's are. Nice work guys  Smiley

I seem to have run into a problem that has stumped me a little though - perhaps one of you guys has some idea what might be causing this error message.

<-- Error message follows  -->

An unexpected exception has been detected in native code outside the VM.
Unexpected Signal : 11 occurred at PC=0xA11C9BD7
Function=XVisualIDFromVisual+0x7
Library=/usr/X11R6/lib/libX11.so.6

This was generated from the last nightly using code that is almost exactly the same as the nvidia refraction demo (except no refraction extensions used here)
This is running on redhat linux with jvm 1.4.1 and an nvidia 5600 with the latest nvidia drivers.

Any advice appreciated.


I also tried it with java version 1.4.2 and I get a different exception as follows

The second stack trace is becoming a common theme Smiley

Seems to be a problem when you're trying to run JOGL with X in 16 bit graphics mode.

This report report here:

http://www.java-gaming.org/cgi-bin/JGNetForums/YaBB.cgi?board=newbies;action=display;num=1062001166

Might be worth adding to the FAQ if its actually the case?

Actually could one of you please file an issue about this on http://jogl.dev.java.net/ ? This is the first report I've personally seen about this problem. Thanks.
