Takeshi Kondo commented on WBRI-195:
------------------------------------

> We are planning a centralized Seam-like @Synchronized solution after interceptors are done 

I don't think that it will resolve this issuse.
Does Seam-like @Synchronized solution mean method call time synchronization?
This issue is construct time synchronization, so @ApplicationScoped doesn't guarantee Singleton.
google-guice has same logic in @Singleton object initialization.
