java.lang.NullPointerException - on queries involving lookup (temp table cache does not have buffermanager set on it)

The following java.lang.NullPointerException is received in ER7 when running queries involving lookup...example query: SELECT IntKey, lookup('BQT1.MediumA', 'StringKey', 'IntKey', IntKey) AS Y FROM BQT1.MediumA ORDER BY IntKey

This seems to only happen when running the production profile. I am getting 57 query failures on most if not all sources and the queries involve lookup.
