Massimiliano Ziccardi Matthias Wessendorf Dimitra Zuccarelli can you take a look. IMO it is because the consumer is not properly closed. I added

 public void beforeShutdown(@Observes BeforeShutdown adv, final BeanManager bm) 

method where I close each injected consumer and it seems to resolve the issue, but I am not 100% sure that's the problem.
