> We have ejb3 entities which use method overiding with java 1.5 covariant return types. The code works correctly in jboss-4.0.4rc1 with ejb3 installed using the installer. 
> However when trying to deploy the same code in the aforementioned version a compilation exception is thrown indicating that there are duplicate methods in the class. The code looks like the following : 
> public abstract class AbstractEntity {
>   protected abstract Object getId();
> }
> public class ConcreteEntity extends AbstractEntity {
>   public String getId() {
>     return id;
>   }
> }
