[vtkusers] vtkPropPicker _very_ slow

I have noticed that vtkPropPicker works much slower than, e.g.,
vtkCellPicker in my code (I use the Java bindings and add one surface
actor to the scene). I have tested vtk-6.1, vtk-6.2 and vtk-6.3-rc2. The
latter two versions I also tried with the OpenGL2 back-end (6.2 crashes
in this case, but that seems to be a known issue, apparently fixed in 6.3).
Here is example time it takes to pick on 1 surface with n points
num. of points 4.5e3 1.5e6
vtkPropPicker 0.152258s 40s
vtkCellPicker 0.005986s 1s
This seems really weird, since vtkPropPicker is supposed to be the
faster one. The difference is quite dramatic and consistent on all VTK
releases I have checked.
Am I doing sth. wrong? Is it my graphics card, or maybe the drivers, or
is it VTK?
I'd appreciate some hints.
