Two instances of @ApplicationScoped bean?
Hi,
I have a UserRegistry bean in my application that is annotated as @ApplicationScoped. It is then injected into a number of service beans. As far as I understand, there should be exactly one instance of the bean created, no? I noticed that, in fact, I have two. The first one is created during the WAR deployment. The second one is created during the first time any service (where UserRegistry is injected) is accessed. My services are CDI beans with HTTP interfaces.
Here's a trace on the first instantiation (this = com.esb.user.UsersRepository$Proxy$_$$_WeldClientProxy@d53240):

Do you have any idea, what is going on?
