Re: Stateless bean injection fails during application server startup

As for the additional details, the chain of events begins with a=20
singleton bean annotated with @Startup that sends messages to a JMS topic=
.

Deferring the message sending (tested with a TimerService) seems to be=20
enough to avoid triggering the problem.

I can try to come up with a reproducer, but it is unlikely that I will=20
succeed, as our current stack is quite complex. However, please feel=20
free to ask any questions or tell me how I can provide the necessary=20
debug information.
