[aerogear-dev] Problems when injecting a Kafka Consumer

Hey, everyone :) As we finished the initial integration of Kafka in UPS, we decided to use a CDI library <https://github.com/matzew/kafka-cdi> to ease the addition of new Kafka consumers/producers. Unfortunately, when I added a consumer by injection (github commit <https://github.com/polinankoleva/aerogear-unifiedpush-server/commit/27961...>) 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. You can find the problems described in JIRA. I really appreciate your help. 1. ComponentIsStoppedException <https://issues.jboss.org/browse/AGPUSH-2145> 2. IllegalArgumentException: object is not an instance of declaring class <https://issues.jboss.org/browse/AGPUSH-2139> 3. InstanceAlreadyExistsException <https://issues.jboss.org/browse/AGPUSH-2140> - I suppose this happens because we never close the consumer. That's why I made a pull request <https://github.com/matzew/kafka-cdi/pull/12> with an addition of shutdown method for the consumer. But not sure where exactly this method has to be invoked. Thanks, Polina
