[vtkusers] vtk (java version) heap memory problem: EXCEPTION_ACCESS_VIOLATION

[Jeff Lee]

Is there an actor/mapper containing this polydata being displayed while 
you are executing the contour filter?  have you already set up the rest 
of the pipeline?  Can you set up the pipeline and update prior to 
calling iren.Start()?
