I often get this problem when using editors that have a vertical ruler for annotations. When scrolling, a multiple IllegalStateExceptions are fired when the annotation images enter the view. Line numbers don't display properly, and text gets mangled. Typically the problem goes away once the editor is closed and re-opened, but it is an annoyance. It is also intermittent and hard to re-produce. I can't find any common cause other than the annotation images (sorry). I am using Eclipse 3.3.1, build I20070621-1340.
