(jogl/cg) jvm crash while initializing cg chader

[MW]

Hi
I'm really puzzled.
I have this example that used to work just fine.  Now 4 ouf of 5 times  JVM crashes with the listing (at the bottom).  Has anyone had a similar problem and are there any suggestions on
how to debug this?

Basically,  I'm stuck with  1.4.2 (using 1.4.2_11-b06).  My  sends a lot of data down to the card through  VBO's.  The cg programs manipulate the data.  This all used to work
pretty reliably.  I'm not sure what changed.  
Some additional info:  I'm running in  WinXP pro, GeForce 7800GTX, latest jogl, cgToolkit 1.5.

Here's the  10,000ft view:

In my renderer,  I call
cgContext = CgGL.cgCreateContext();
after the init(GLAutoDrawable) has been called.

Then the renderer loads the shader:
- checks the profiles (and this is supposedly where it breaks)  [vp30/vp40  same thing happens]
- if it gets past this point than things seem to work fine

Again, I'm at a loss, and would appreciate some suggestions.
Thanks!
