Jogl Viewer Texture Bug

Hi, this is probably for Charles: I have problems using textures. If I change the texture image of a geometry a few times or if I show frequently changing lables. I run into the following Exception pretty soon:

Code: Select all

This is very annoying as one has to restart the program after such an exception to continue working with textures. The machine which I'm working on is:

I have had some problems related to textures on my relatively new Macbook Pro recently which I solved by backing out changes to the jreality jogl package to mid-summer. Please try that first.

Then if you still have the problem, please try to isolate example code that displays the problem. I'm not seeing this error in the code I'm running right now.
