> ByteString does not deserialize properly as a FetchRequest parameterValue
> -------------------------------------------------------------------------
>
> Key: CALCITE-671
> URL: https://issues.apache.org/jira/browse/CALCITE-671
> Project: Calcite
> Issue Type: Bug
> Reporter: Nick Dimiduk
> Assignee: Julian Hyde
> Attachments: 671.patch
>
>
> I think the reason here is that FetchRequest#parameterValues is declared as a
> List<Object>, which Jackson interprets as a request to serialize as plain
> objects (see [Deserializing, other|http://wiki.fasterxml.com/JacksonFAQ]).
