Hi Bernhard,
actually the point is that in line 4 you're requesting to load all the
features in memory, which may be isn't what you really wanted.
try doing just
col = features.getFeatures();
instead of
features.getFeatures().collection();
That way you'll obtain a "streamed" feature collection, whose contents you can
traverse by asking it for an iterator:
FeatureIterator it = col.features();
Hope that helps,
Gabriel.
