when do a query with setFirstResult on derby, Exception like below be thrown

[javatest.batch] ERROR: This method should only be called on ResultSet objects that are scrollable (type TYPE_SCROLL_INSENSITIVE).
[javatest.batch] javax.persistence.PersistenceException: org.hibernate.exception.GenericJDBCException: This method should only be called on ResultSet objects that are scrollable (type TYPE_SCROLL_INSENSITIVE).

by dig into the code, in

org.hibernate.loader.Loader#prepareQueryStatement

the "scroll" is false, and useScrollableResultSetToSkip is "true", so, the scroll model comes from queryParameters, which is null.
