Hi Andrea,
thanks for the fast reply!
I've checked everything, but really every iterator in the code is closed after
usage.
But, I've seen now that at the end of error lines stated in my last mail, there
are further errors:
Okt 01, 2013 4:04:34 PM org.geotools.map.Layer finalize
SEVERE: Layer dispose not called; possible memory leak
Okt 01, 2013 4:04:34 PM org.geotools.map.Layer dispose
SEVERE: Layer preDispose was not called prior to calling dispose
(I didn't notice them before because the huge amount of error lines flush the
console..)
Why does this error occur, respectively, how can I dispose layers?
Thanks,
Philipp

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.
Close on all opened feature iterators. By looking at the above, you still have
some that are left open
Cheers
Andrea
