Steven Hawkins resolved TEIID-5068.
-----------------------------------
Resolution: Done
The translator will no longer use toatom for the object cast, and the retrieval is updated to use just a get not a getObject.
It's not done by the metadata processor, but it looks like Kylin wanted to allow the direct retrieval of json values as clob. We can leave that as an undocumented feature for now.

> Key: TEIID-5068
> URL: https://issues.jboss.org/browse/TEIID-5068
> Project: Teiid
> Issue Type: Bug
> Components: Misc. Connectors
> Affects Versions: 8.12.x-6.4
> Reporter: Jan Stastny
> Assignee: Steven Hawkins
> Priority: Critical
> Fix For: 10.0, 8.12.x-6.4, 9.3.4
>
>
> There seems to be issue with casting to biginteger datatype.
> It applies to both cases:
> # Model column as integer in Source model, CAST to biginteger in a View
> # Model column as biginteger in Source model
> In both cases a ClassCastException is thrown.
> Here I provide the artifacts first case:
