Netbeans Swing UI designer - what does the hazard icon mean?

Netbeans Swing UI designer - what does the hazard icon mean?

I'm working in the Design view of a Swing application and occassionally I
see a small hazard warning symbol appear in the top corner of a component.
I assumed this was something to do with visibility overlap or similar but
having adjusted things I can't match a guess against anything credible.
Unfortunately it doesn't have a tool-tip and does not react to any mouse
clicks.
Any ideas? Google does not seem to suggest anything either.
