ClassCastException during hash join (can not be cast to TermId)

    Details

      Description

      This was observed for BSBM BI Q5.

      The problem is that the hash joins were attempting to stick an IVCache's Value into a BTree modeled after the TERMS index when it was an INLINE value. We put TermIds into a mock TERMS index and BlobIVs into a mock BLOBS index in order to support the hash join. But an XSDInteger was getting stuff into the mock TERMS index and that was throwing a class cast exception.
