Mark Struberg commented on OWB-436:
-----------------------------------

I've commented a unit test and a quick fix solution for our problem.

This isn't yet perfect, so I'll create a follow up Jira for improving the 
handling.

> Our code which triggers the creation of contextual instances in 
> AbstractContext is not thread safe.
> This first did hit me while starting a Web Server while running under full 
> request load. This did lead to 40 parallel threads trying to startup my 
> @ApplicationScoped services. A few of those services do some logic in 
> @PostConstruct and therefore take some time, which resulted in creating those 
> @ApplicationScoped beans multiple times!
