Description

Calcite treats it as SCALAR (due to JavaRowFormat.optimize), thus field access does not work.

public final IntHolder[] primesCustomBoxed =
        new IntHolder[]{new IntHolder(1), new IntHolder(3), new IntHolder(5)};

  @Test public void testCustomBoxedScalar() {
    CalciteAssert.that()
        .with("s", new ReflectiveSchemaTest.CatchallSchema())
        .query("select \"value\" from \"s\".\"primesCustomBoxed\"")
        .returnsUnordered("1", "3", "5");
  }

Caused by: arrays first differed at element [0]; expected:<[1]> but was:<[value=org.apache.calcite.test.ReflectiveSchemaTest$IntHolder@2aa3cd93]>
