> In RelBuilder, can't get group field by name: "field [ENAME] not found;".
> The regression is spotted in 1.22.0 RC 3. The test works fine in 1.21.0
> branch.

> {code:java}
> @Test public void testGetGroupFieldByName() {
> final Function<RelBuilder, RelNode> f = builder -> {
> RelBuilder aggregated = builder.scan("EMP")
> .project(builder.field("EMPNO"), builder.field("ENAME"),
> builder.field("SAL"))
> .aggregate(
> builder.groupKey(builder.field("ENAME")),
> builder.sum(builder.field("SAL"))
> );
> RexInputRef groupFieldReference = aggregated.field("ENAME");
> assertThat(groupFieldReference.getIndex(), is(0));
> return aggregated.build();

> final String expected =

> " LogicalProject(EMPNO=[$0], ENAME=[$1], SAL=[$5])\n" +
> " LogicalTableScan(table=[[scott, EMP]])\n";
> assertThat(f.apply(createBuilder(c -> c)), hasTree(expected));

> Error (1.22.0 RC 3):
