I am new to Geotools and starting to go through all of the samples and
tutorials that I find in the user guide. I have run into a bit of an issue
when I
try to look at various shape files using ShapeLab. Fairly often when I
select a shape file to view I get numerous failures as the module is
attempting
to paint the screen. The failures are all the same. Just one after the
other. Here is an example:

I am still new enough to Geotools to struggle with knowing which direction
to take when attempting to debug a problem. What should I look for here?
What can cause this problem. It occurs when I set the frame to visible and it
starts painting.
