In this order ?
Or is D started first, and then C, then B and finally A ?

After a little digging in our code ,I've seen something wrong, but it
does not explains the behavior at first glance...
In EZB, we have the concept of BindingFactory, that manage how we
publishes business interfaces of the beans.
So there is a default one, that manages JNDI. And for OSGi, we added an
OSGiBindingFactory. This is that class that register/unregister services
for your bean's interfaces.
This factory is added in a singleton BindingManager.
It's added during the core component startup, but it's never removed.
You see where I wanna go ?
if you start multiple cores, the OSGiBindingFactory will be registered
multiple times, with the effect of adding 2 more services (1 for @Local
1 for @Remote) for each of your beans ...

So the question is: "Do you start multiple cores ?"

Cheers
