[vtkusers] Problems with vtkVectorText and vtkFollower in Java

[Jeff Lee]

Hi,
I ran your code and Grid2 shows text.  Grid1 shows spheres and Grid2 
shows text.  I use text all the time, but have abandoned vtkTextFollower 
in favor of vtkTextActor.  The examples in Wrapping/Java/AxisActor.java 
show how to do this.  You could try to run TestVTKCanvas and see if you 
get text.  If not, perhaps your build is corrupt.
