I have a problem with the a "J3D-GeometryStructureUpdateThread-1" java.lang.NullPointerException. It occurs when moving BranchGroups within the scene graph (using the method "moveTo" of the "Group" class) upon a mouse clicking event.
The BranchGroup that is being moved within the scene graph has a collision detection behavior attached, which seems to be the reason for the exception. The below attached stacktrace indicates that the collision detection processing leads to the exception.
As the above exception does not occur every time the user clicks, I assume that it's a synchronization issue within Java3D.
Any work arounds or bug reports known?
Thanks so much
Full exception (using Java3d 1.5.):
