An intervals source of the following type:
{code:java}
IntervalsSource source = Intervals.ordered(
Intervals.or(Intervals.term("term1"), Intervals.term("term2")),
Intervals.term("term3")){code}
can cause an infinite loop when queried, due to a bug in the 'no more
intervals' logic in DisjunctionIntervalIterator
