I know this is a weak bug report and I apologize in advance for that...
I'm writing integration tests for my solver configuration. My code seems to work in my GUI (subclass of CommonApp) but it fails under my junit test. I'm quite new to Drools and Planner so I wouldn't be surprised if the root cause is my fault, but I think a NPE is bad news.
