hello all, as an update on this issue: using GeoTools 2.5.3 (instead of 2.4.4) and communicating with a GeoServer 1.6.4b, i was able to get the test case running (a) without exceptions, and (b) demonstrating proper handling of the 'matchCase' attribute in string-based comparison filters when using WFS version 1.1.0 even on a shapefile based data store. i'm including at the end an updated version of the test case in the hope that it may be of help to somebody else facing the same situation.
