I keep getting errors like this in my program, and I can't reproduce
them in specific instances. My code isn't mentioned anywhere in this
strack trace, and I'm not sure where to start debugging this. This is
under 1.4.1_01, but it does it under older versions as well. Any
ideas?

javax.swing.text.StateInvariantError: GlyphView: Stale view:
javax.swing.text.BadLocationException: Invalid location

You didn't say what you are doing when the errors occur. I distinctly
remember seeing and dealing with this IllegalStateException in our own
code base... and if you'll let me know when it occurs, perhaps I can
scan around for code to fix it.

First of all check the thread safety aspect of your code. I've seen
similar things occur when you try to mutate a Document (which is the
model for JEditorPane/JTextPane etc) from a thread other than the Event
Dispatch Thread.

I was able to narrow it down by disabling a call to setText() on a
JEditorPane, which was being called by a different thread. Of course,
I want this thread to call setText(). Did you find a workaround?

That's what SwingUtilities.invokeAndWait and SwingUtilities.invokeLater
are for. Use them.
