> If we apply non-substitution rules first, some tests in TopDownOptTest would fail and it's not supposed to be. It can be reproduced by the following change:
> {code:java}
> // TopDownRuleQueue.java
> private void addMatch(VolcanoRuleMatch match, Deque<VolcanoRuleMatch> queue) {
> if (!names.add(match.toString())) {
> return;
> }
> if (planner.isSubstituteRule(match)) { // change this line
> queue.addFirst(match);
> } else {
> queue.addLast(match);
> }
> }
> {code}
> The error message is:
> {code:java}
> java.lang.AssertionError
