I might add:
This error does not occur when using geotools 9.5. Using 10.x or 11.x, it
happens again.

Dears,
I am testing SelectionLab.java, which is copied from
http://docs.geotools.org/latest/userguide/tutorial/map/style.html
When selecting the "select" cursor and clicking on the map, console prints
following errors:

It happens at:
SimpleFeatureIterator iter = selectedFeatures.features();
in selectFeatures()
Does anyone come across similar things?
Thx.
