Sorry for not being specific last time, I got the Stackoverflow error while selecting a Sofa view at the bottom of the viewer.
I first suspected this was caused by a Java update because I don't remember I've done any UIMA updates. However, after a few trials I found that it is actually due to a uimaj-tools update. The Sofa selection works well until uimaj-tools 2.7.0. The stackoverflow error can be found on both v2.8.0 and v2.8.1, which I believed are the most updated version on Maven. I think it can be reproduced by using the AnnotaitonViewer of v2.8.0, and change a sofa. I am currently rolling back to v2.7.0, but I think this problem is worth nothing. Best, Hector
