> Hi,
> when doing Load Tests, we  recognize that we sometimes got stuck in an infinite loop, when calling the _handleListenerForAnnotations method of the ApplicationImpl class. According to our analysis, this is related to the _classToListenerForMap attribute that is is defined as plain HashMap, so no synchronisation takes place when it is accessed from several threads. Our suggestion would be, to define it as a ConcurrentHashMap instead, because according to our experience, such kind of infinite loops due to concurrency don't occur with ConcurrentHashMaps.
> Kind regards,
