Description

When calling the ObservationManager.getRegisteredEventListeners() a NullPointerException may be thrown if no event listener has been registered (yet). The reason for this is, that in the ClientObservationManager.getRegisteredEventListener method an internal field is access directly, which is created on demand and thus may be null.
