Unfortunately, when I added a consumer by injection (<a href="https://github.com/polinankoleva/aerogear-unifiedpush-server/commit/27961bc29f3be817faaf845baa2893a32eeae3da" target="_blank">github commit</a>) I encountered three problems. I have tried to do my best to figure them out but I still have no clue for them. They all happen after a redeployment of the UPS, so I suppose there is a problem when a consumer is destroyed/created again. </div><div><br></div><div>You can find the problems described in JIRA.

That's why I made a <a href="https://github.com/matzew/kafka-cdi/pull/12" target="_blank">pull request</a> with an addition of shutdown method for the consumer. But not sure where exactly this method has to be invoked. </div><div><br></div><div>Thanks, Polina</div></div>
