Yes, but those other methods are actually for the software renderer only...i somehow doubt that you are using them. Another place is when you are adding a TextureInfo with a faulty id in it. At that stage, i don't know any texture names. You have to check the getTextureId() for it's return value in that case (assuming that you are using this to create the TextureInfo).
I've updated the jar with a version that adds the name to the mentioned methods, but as said, i doubt that this causes your problem.
