when i run those code as below, i got some error messages.

{code:java}
//MaterializationTest
@Test public void testJoinToJoin0() {
    String mv = ""
        + "select \"deptno\" from\n"
        + "\"emps\" intersect select \"deptno\"  from \"depts\"";
    String query = ""
        + "select \"deptno\" from\n"
        + "\"depts\" intersect select \"deptno\" from \"emps\"";
    checkMaterialize(mv, query, true);
  }
{code}

java.lang.AssertionError: 
Expected: a string containing "EnumerableTableScan(table=[[hr, m0]])"
     but: was "PLAN=EnumerableCalc(expr#0..1=[{inputs}], expr#2=[2:BIGINT], expr#3=[=($t1, $t2)], deptno=[$t0], $condition=[$t3])\n  EnumerableAggregate(group=[{0}], agg#0=[COUNT()])\n    EnumerableUnion(all=[true])\n      EnumerableAggregate(group=[{0}], agg#0=[COUNT()])\n        EnumerableTableScan(table=[[hr, depts]])\n      EnumerableAggregate(group=[{1}], agg#0=[COUNT()])\n        EnumerableTableScan(table=[[hr, emps]])\n\n"
