---------------------------------------------------------------
It seems the issue is somehow related to CALCITE-2402 fix, in which we changed
some codes converting calls of cast function from
{{StandardConvertletTable.java}}.
IMHO this requires just some minor follow-up changes, so let's see if we can
bring the fix to 1.20.0.
