Harald Wellmann commented on DELTASPIKE-578:
--------------------------------------------

Just ran into this issue while load testing my application. It's easy to reproduce and there's no obvious workaround for consumers, so the priority should be raised.

> The lazy init process is not thread safe. In particular the code checks if entityManagerResolverIsNormalScope is null to determine if the entity is initialised, however this is set before the initialisation is actually completed, meaning a thread can get an uninitialized component, which then causes problems. 
> The initialize() call should be moved up to before entityManagerResolverIsNormalScope is set.
