> Basically  CALCITE-4610  but this time with a CASE WHEN. 
> I can provide a repro test if needed, but any join with a condition like in that same test
> {code:java}
> CASE WHEN a = 'some_literal' THEN true ELSE c = 'some_other_literal' END{code}
> The CASE travels through the pipeline, and the RelToSqlConverter crashes on it in convertConditionToSqlNode.
