-------------------------------------
Description:
I had no idea which class file it's expecting the room property on in this error message.
I 'll needed to look for a needle in a haystack:

Reproduce recipe:
- take meeting scheduling example in optaplanner-examplse
- remove getters and setters for room in MeetingAssignment.java
- remove all rules in the drl (to avoid it crashing on something else sooner), especially those that involve the room.
- the error occurs when DroolsScoreDirector.update(meetingAssignment, "room") is called
