May two different gbeans have the same name in a configuration

[Jacek Laskowski]

Hi,

I wonder why two different GBeans of org/apache/geronimo/Security 
configuration have the same name:

<gbean name="properties-login"
class="org.apache.geronimo.security.jaas.LoginModuleGBean">
...
</gbean>

<gbean name="properties-login" 
class="org.apache.geronimo.security.jaas.JaasLoginModuleUse">
...
</gbean>

Is there a difference if I wanted to look up the first using JMX or 
available query mechanism through the kernel?

Jacek
