Long primary keys

Hi,

I'm running a Oracle database and trying to get Cayenne to work when having primary keys that should be mapped to Long in Java. The data type in Oracle is NUMBER(38), but when I create a SelectQuery and use DlpObject object= (DlpObject) Cayenne.objectForQuery(ctx, this); to get the object, I get the exception below. I'm using Cayenne version 4.0.2. Why does Cayenne think that the type is Integer,  and how can the issue be resolved?
