---------------------------------------
Found while testing CALCITE-7791
> CompileException casting a ROW array literal to Object[]
> --------------------------------------------------------
>
> Key: CALCITE-7831
> URL: https://issues.apache.org/jira/browse/CALCITE-7831
> Project: Calcite
> Issue Type: Bug
> Components: core
> Reporter: Sean Broeder
> Priority: Major
>
> CAST(ARRAY[ROW(1)] AS ROW(a INTEGER) ARRAY) fails at runtime on main
> select * from unnest(cast(array[row(1)] as row(a integer) array))
> throws:
> org.apache.calcite.runtime.CalciteContextException: ...
> Caused by: org.codehaus.commons.compiler.CompileException:
> Cannot cast "Baz$Record1_0" to "java.lang.Object[]"
>
> The validator and SqlToRelConverter both handle this literal correctly
> in CALCITE-7791, but code generation for the runtime CAST from the
> literal's generated record class to Object[] is broken, so no end to end
> test can use this literal.
