Description Ansgar Radermacher CLA 2017-04-28 08:34:48 EDT 
Stereotype applications can be broken, e.g. since the profile has evolved. While the profile migration assistant can handle some of the problems, it does not handle all. This is problematic, if stereotype attributes are shown in the diagram.
I had the following exception when I opened a diagram of an existing model (migration assistant did not propose a migration).

java.lang.NullPointerException
