If a SFSB is looked up the server create a Instance of the bean and invoke the @PostConstruct method.
The first call of a business method throw an error EJBCLIENT000051 [1] and because of this the bean can never being removed.

The reason for this is that the SFSB does not have an interface marked as @Remote.

The client should throw an Exception during lookup and the server should not create an instance in that case.
