[vtkusers] VtkPanel in java vtk bindings not being collected?

[Sebastien Jourdain]

There is a Delete() method on it. But on Linux, vtkPanel leak to prevent a
crash.

  public void Delete() {
    if(rendering) {
      return;
    }
    rendering = true;
    // We prevent any further rendering

    if (this.getParent() != null) {
      this.getParent().remove(this);
    }
    // Free internal VTK objects
    ren = null;
    cam = null;
    lgt = null;
    // On linux we prefer to have a memory leak instead of a crash
    if(!rw.GetClassName().equals("vtkXOpenGLRenderWindow")) {
      rw = null;
    } else {
      System.out.println("The renderwindow has been kept arount to prevent
a crash");
    }
  }
