Description

When there are multiple predicates in RexSimplify, only the first predicates will be used to simplify the RexNode. The following test can reproduce.

// RexProgramTest.java
@Test public void testSimplifyRangeWithMultiPredicates() {
  final RexNode ref = input(tInt(), 0);
  RelOptPredicateList relOptPredicateList = RelOptPredicateList.of(rexBuilder,
      ImmutableList.of(gt(ref, literal(1)), le(ref, literal(5))));
  checkSimplifyFilter(gt(ref, literal(9)), relOptPredicateList, "false");
}
