Description

Testcase:

 /*  RexProgramTest */
  @Test public void testInDigest() {
    RexNode e = in(vInt(), literal(1), literal(2));
    assertThat(e.toString(), is("IN(?0.int0, 1, 2)"));
  }
 /*  RexProgramBuilder */
  protected RexNode in(Iterable<? extends RexNode> nodes) {
    return rexBuilder.makeCall(SqlStdOperatorTable.IN,
        ImmutableList.copyOf(nodes));
  }

The exception is due to that it tries to look at the other operand https://github.com/apache/calcite/blob/883666929478aabe07ee5b9e572c43a6f1a703e2/core/src/main/java/org/apache/calcite/rex/RexCall.java#L115

SIMPLE_BINARY_OPS contains COMPARISION which also contains "IN"

this was introduced in CALCITE-2454 a few days ago; bug not released
