Carlos,

For the (possible) root cause of this problem, rf:

As to the solution, well, all I can say is that when I've got this error in the
past, it was due to my Java app calling a render method and not invoking the
"proper" render methods (with locks) provided by Jeff Lee in vtkPanel.java .
 Jeff, or someone else, would have to answer the question of which version of
VTK has the correct version of vtkPanel.java to handle this.

Good luck.
