How should a Canvas3D be closed when closing the associated JFrame to free resources?

Here's what we're doing now:

from a WindowEvent (closing) so on the EDT:

   View.removeCanvas3D()
   View.attachViewPlatform(null)  // was recommended in earlier versions of Java3D
   Universe.removeAllLocales()

   Locale->BranchGroup.detach()  // top level scene branch

   Frame.dispose()

Can you recommend a better procedure?

But I'm not sure why the computer monitor would blank out before opening a JFrame with a Canvas3D.  This
was with pre9, so I will verify with pre11.
