[vtkusers] Crash in vtkShaderProgram/vtkOpenGLPolyDataMapper

[dei]

Just to reiterate, I want to use VTK-7.0.0 to display very large Wavefront
.OBJ meshes within a complex java CT medical application. My simple java
viewer test apps work fine (since I fixed a "mouse-move before
initialization complete" crash - see above). However, more often than not,
the CT app crashes during VTK initialization. When it initializes
successfully, it works flawlessly.
I have more info about the problem:

1.  The problem occurs on different 3 PCs with 2 different graphics cards.
All support OpenGL 4.x

2.  When the crash occurs, the vtkError.txt log shows:
      ERROR: In ..\..\..\Rendering\OpenGL2\vtkWin32OpenGLRenderWindow.cxx,

3.  All accesses to the VTK occur on the AWT-EventQueue-1 thread. 

4.  Changing the order and timing of VTK initialization relative to the
display of the VTK JPanel does not appear to fix the problem.

5.  VTK-6.3.0 does *not* exhibit the crash, but it is slow to render when
moving or zooming the mesh. My simple test apps *have no problem rendering
the same mesh* when using VTK-6.3.0. This should tell me something, but I'm
not sure what.
