CGLIB reuses the same class definition if it has the same properties. This can happen on a doc/lit service when there is more than one method with the same arguments.

As an example this fails:
@Stateless
@WebService(endpointInterface="org.jboss.tutorial.webservice.bean.Calculator")
public class CalculatorBean
{
public int add(int x, int y)

{ return x + y; }

public int subtract(int x, int y)

{ return x - y; }

}
