Ejb3 deployer does not allow method overriding with Java 1.5 Covariant return types
-----------------------------------------------------------------------------------

                 Key: EJBTHREE-684
                 URL: http://jira.jboss.com/jira/browse/EJBTHREE-684
             Project: EJB 3.0
          Issue Type: Bug
    Affects Versions: EJB 3.0 RC8 - FD
         Environment: Jboss-4.0.4.GA with ejb3 installed using the installer 'jboss-4.0.4.GA-Patch1-installer.jar'
            Reporter: Swarn Dhaliwal


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;
  }
}
