I was using debug level tracing, changed it to trace.
The above two printlines appear after the last accepted move, before the
exception is thrown:
17-07-13 17:13:51 TRACE - DefaultDecider                 -         Move
index (118), score (0hard/-121soft), accepted (true) for move (Conversation
4: Family 4, Student 4, Teacher 1, Timeslot 2(Day 1) => Timeslot 14).

I'll look into creating a reproducer for a jira issue.
