I have a local iface like so

@Local
public interface UserDao {

 public User authenticate(String username, String password);

}

And an implementation like so

@Stateless(name = "UserDao")
public class UserDaoImpl extends DaoBase implements UserDao {

 public User authenticate(String username, String password) {
 return get(User.class, "User.authenticate", username, password);
 }

}

and the DaoBase class like so

public abstract class DaoBase {
 <U> U get(Class<U> clazz, String queryName, Object... params) {
 //does stuff here
 }
}

yet for some reason, when my EJB impl accesses a package private method on the super class, I get an exception:

java.lang.IllegalAccessError: tried to access method [package].DaoBase.get(Ljava/lang/Class;Ljava/lang/String;[Ljava/lang/Object;)Ljava/lang/Object; from class [package].UserDaoImpl

The way it is executed is from a seam-based war (deployed in a different ear on the same app server). The reference to this SLSB is obtained over JNDI. The war has a client jar for the aforementioned EJB w/out the implementation.

This worked on JBoss 4. Any idea what I am doing wrong on JBoss 5 to prevent package private super-class method access from my implementation?
