When creating two or more conversation scoped beans, the creation of the second bean will block until any method annotated with @PostConstruct is finished.

In my example WAR project I have two JSF pages: one accesses a conversation scoped bean that sleeps for 10 seconds in a method annotated with @PostConstruct. The other accesses a conversation scoped bean that does not have any method annotated with @PostConstruct.

While the first page is loading, the second page will be unable to finish, because bean creation is blocked completely.

The lock seems to be acquired here:

... and postconstruct is called here:
