Hi Marcel, Memory leaks will happen when there are background threads started by webapp and not shutdown (usually lib like Code hale has shutdown hook, but web app you do get to execute shutdown hook so you get memory leaks or class not found). I have faced this so you need to either use web context listener and close all threads.
With Old Producer I have faced this issue. I had to explicitly called Metrics.defaultRegistry().shutdown(); for shutdown because producer.close() does not shutdown metics threads. Similar issue if you are consuming consumer side. Also, you have to call consumer.shutdown() as well. I hope this help !
