Description

When a parameter in EJBQLQuery is set to null, an error occurs which results in ClassCastException. When parameter is not null query is executed as expected.
It is duplicable with following/similar code:

EJBQLQuery eq = new EJBQLQuery("SELECT COUNT(u) FROM User u WHERE u.username like :usernam AND u.userInfo.name like :userName");
eq.setParameter("userName", null);
eq.setParameter("usernam", "msabo");
return (Long) DataObjectUtils.objectForQuery(getObjectContext(), eq);

Full stack trace is in attachment.
