Deploy ejb failed

[lpoliver27]

I just installed Jboss4.0.5 with no error. When I deployed my application ejb, it failed. The application ejb runs well on my previous server and they are EJB2.0. I compiled it with the late javeEE lib and unchange the ejb-jar.xml. They are all session beans. When I depolyed them, Jboss gave me the following error:
14:52:04,026 WARN [verifier] EJB spec violation:
Bean : SYS/User
Method : public abstract MutableUser addMobileTagUser(MutableTagUser, int, boolean) throws CodeException, RemoteException
Section: 7.10.5
Warning: The methods defined in the remote interface must have a matching method in the bean's class with the same name and same number and types of arguments.

I found it. Exactly the bean metthod is not same as the remote metthod.

MutableUser addMobileTagUser(MutableTagUser, int, boolean) throws CodeExceptiont

is not same as bean method. In bean class, it used MutableTagUser super class instead of MutableTagUser. But there was no error when we deployed our application in a old ejb container.

Is it a bug with the old container?

Thanks.
