ScrollableCursor
with the same named native query.

org.eclipse.persistence.queries.SQLCall incompatible with
java.util.Vector

Mech
anism.executeSelectCall(DatasourceCallQueryMechanism.java:29
9)
Once the named native query with ScrollableCursor is
invoked,
the getResultList of the following same named native query
resulted into the ClassCastException.

Local fix

By using the different named native query or non-native query,
the issue didn't happen.
