UML 2.0, which is the standard modeling language for object-oriented systems, has only an informally given semantics. This is in particular the case for UML 2.0 state machines, which are widely used for modeling the reactive behavior of objects. In this paper, a list of 29 newly detected trouble spots consisting of ambiguities, inconsistencies, and unnecessarily strong restrictions of UML 2.0 state machines is given and illustrated using 6 state machines having a problematic meaning; suggestions for improvement are presented. In particular, we show that the concepts of history, priority, and entry/exit points have to be reconsidered.
