Hi everyone,
my Geotools app to plot country-related data to pngs is working quite well
now, but when I create many instances of its base class one after another for
batch plotting, I'm getting this error after a while (10-20 instances of ca.
300 to come):

over and over. And the rendered pngs contain only some of the countries, many
are missing.
Might it be some kind of memory leak?
I already googled this, and found that it's necessary to call close(); on all
opened features; I did this, but the error still remains.
All instances access the same .shp-file. Can this be a problem?
It's strange because every instance of JMapFrame is disposed before the next
one is called... do I have to manually close/dispose other objects than
features or JMapFrames?
Does anyone have an idea what might cause that?
Thanks in advance, cheers,
Philipp
