You should only update a stateset, drawable, or the scene graph structure from the update traversal, update callback, or update operation. Are you modifying anything at runtime?
Outside of the Optimizer, DataVariance has no effect in SingleThreaded mode. It also has no effect on Nodes (only Drawables and StateSets). So it's more likely that you are trying to modify the scene graph from another thread without proper synchronization.
