The message is from Motif, and is probably a semi-corner case that the
AWT doesn't handle very well. Motif is pretty particular about
consistency between scrollbar parameters (min, max, value, etc.) and my
guess is that some pretty common situations are causing AWT not to do a
good job of setting up Motif scrollbars.

I see the message frequently; many do. Maybe your app (and thousands of
others) are setting some inconsistent scrollbar parameters, but since
the message often appears with automatic scrollbars that's very
unlikely. Based on past Motif experience, I'd expect this problem to be
particularly likely if you've got some scrollbars set up to scroll an
object smaller than the viewport.
Solutions? There's always Swing.
