Currently I'm creating a new installer for a Java 3D application using
Install Anywhere and I've run into an interesting bug.
The program works correctly when ran from Eclipse with the 1.4.2_03 J2SDK
and OpenGL version of Java 3D. If I create an installer with the 1.4.2_03
J2SDK for DirectX, the application also works correctly, but if I create
an installer using OpenGL, the program ceases to respond and I have to
shut it down from the task manager even though everything works in
Eclipse.
The error occurs during an update of a texture.
It has been very time consuming to debug, since I have to create a new
installer everytime I test the program, but I've found that the program
crashes inside the ImageComponent2D.Updater class's updateData method.
I've included the code below, and am using JOptionPane's to debug the
application (anyone know of a better way?). The statement that crashes is
marked below, so please help me if you know what might be wrong with the
code. I have no idea why it would work in Eclipse, but not when installed
using OpenGL, so any thoughts on this would be helpful also.
Thank you,
Jason Cheatham
