> When there are multiple predicates in RexSimplify, only the first predicates
> will be used to simplify the RexNode. The following test can reproduce.
> {code:java}
> // 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");
> }
> {code}
