Okay, if this is intended.
It was just a stumbling block.
I will look if I can change our code with backward compatibility.

The criteria for this issue was build by using the table column name
'PHB_USRID'.
After I changed this to 'addIsNull("m_iUserId") the query succeeded.
Here is some code:
public static Collection getPublic()
{
Criteria criteria = new Criteria();
criteria.addColumnIsNull("PHB_USRID");
PersistenceBroker broker =
PersistenceBrokerFactory.defaultPersistenceBroker();
QueryByCriteria query = new QueryByCriteria(A1.class, criteria);
query.setDistinct(bDistinct);
return broker.getCollectionByQuery(query);
}
/**
*
* @ojb.class table="A1"
*/
public class A1 {
/**
* @ojb.field column="PHB_ID"
* primarykey="true"
* autoincrement="ojb"
* id="1"
*/
protected Integer m_iId;
/**
* @ojb.field column="PHB_NAME"
* jdbc-type="VARCHAR"
* length="50"
*/
protected String m_sName;
/**
* @ojb.field column="PHB_USRID"
*/
protected Integer m_iUserId;
}
/**
* @ojb.class table="A0"
* include-inherited="false"
* @ojb.field column="PHB_ID"
* primarykey="true"
* name="m_iId"
* jdbc-type="INTEGER"
* @ojb.reference class-ref="A1"
* auto-retrieve="true"
* auto-update="true"
* auto-delete="true"
* foreignkey="m_iId"
*/
public class A0 extends A1
{
/**
* @ojb.field column="PHB_CSV"
* jdbc-type="VARCHAR"
* length="255"
*/
protected String csv;
}
I hope it is enough, because I can't post pure company code.
