[vtkusers] vtkVectorText or vtkFollower Bug

[Jeff Lee]

works fine for me, vtk4.0cvs and java1.4 on linux.  had to insert
  static {
    System.loadLibrary("vtkCommonJava");
    System.loadLibrary("vtkFilteringJava");
    System.loadLibrary("vtkIOJava");
    System.loadLibrary("vtkHybridJava");
    System.loadLibrary("vtkImagingJava");
    System.loadLibrary("vtkGraphicsJava");
    System.loadLibrary("vtkRenderingJava");
  }
