@Startup annotation and init-on-startup element in ejb-jar.xml aren't merged into metadata correctly

Consider the following bean:

@Singleton
@Startup
public class StartupBean
{
...
}

and the corresponding ejb-jar.xml:

...
<session>
  <ejb-name>StartupBean</ejb-name>
  <session-type>Singleton</session-type>
  <ejb-local-ref>
   ...
  </ejb-local-ref>
</session>

Notice that the ejb-jar.xml is used to configure some other aspects of the EJB, but it doesn't set/override the init-on-startup attribute of the bean. Effectively, the StartupBean should still be considered as a init-on-startup bean.

However, this isn't the case currently. During merging of this annotation and xml metadata, the merged metadata turns up the StartupBean as a normal non init-on-startup bean. See the referenced forum thread for the complete details.
