The EJB 3.0 Spec states the following in section "4.6.2 Session Bean Class":

"The session bean class may have superclasses and/or superinterfaces. ......
A session bean class must not have a superclass that is itself a session bean class."

Problem Description:

According to the ejb-jar.xml, this is an ejb 3.0 ejb-jar:
<?xml version="1.0" encoding="UTF-8"?>
<ejb-jar xmlns="http://java.sun.com/xml/ns/javaee"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/ejb-jar_3_0.xsd"
version="3.0">

</ejb-jar>

So, we have an EJB 3.0 application. Yet, we see declared:

@Stateful
public class Farmer implements FarmerLocal {

and

@Stateful
public class LazyFarmer extends Farmer implements LazyFarmerLocal, FarmerLocal {

Farmer being extended by LazyFarmer violates the spec mentioned above. I believe this is allowed in the 3.1 spec, but not the 3.0 Spec.
