Nope. If you look at the stack trace, you see that the exception was thrown
after trying to figure out a GraphicsConfiguration.
i.e., the following code returns null :
GraphicsConfigTemplate3D template3d = new
GraphicsConfigTemplate3D();
return
GraphicsEnvironment.getLocalGraphicsEnvironment().getDefaultScreenDevice().g
etBestConfiguration(template3d);
So there are two possibilities:
1. Your laptop doesn't have a 3d graphics card - sorry, there's nothing to
do but to change the graphic card or the laptop.
2. You have a 3d graphic card, but the graphic device that VMWARE is
providing does not support 3D - try directly the linux environment.

It looks to me that this has nothing to do with VMWARE at all, I suspect
that you have an older version of java3d on your old box, one that doesn't
complain about a null GraphicsConfiguration in the Cavas3D constructor. If
you read the error message it tells you exactly what is going on. You need
to get a GraphicsConfiguration object to pass into the constructor for
Canvas3D

It looks like it already throws that null pointer (I can't check right now)
follow the comments in the javadoc and initialise it, then let us know if
that fixes it.
