line: 1287 Reproducible: Always Steps to Reproduce: 1. Create a class diagram 2. Create a new Query artifact in class diagram 3. Change the name and click on Finish 4. Query artifact doesn't yet have a return type, but we still query its return type assuming that it does. This leads to the above NPE.
