According to the Java EE 6 spec, is the @PostConstruct method on a singleton startup bean allowed to block, or must it return ASAP?
It’s not forbidden to block, but I think the container startup procedure will block too.
The specs just say in section 4.8.1 “Singleton Initialization” that:
So if the
@PostConstructmethod doesn’t exit, the container is not ready to serve client requests.
