> When _doStart_ is called on ConsulEventConsumer it first [calls|https://github.com/apache/camel/blob/camel-2.21.1/components/camel-consul/src/main/java/org/apache/camel/component/consul/endpoint/ConsulEventConsumer.java#L54] _doStart_ of a superclass _AbstractConsulConsumer_ when _scheduledExecutorService_ is not initialized yet.
> EventWatcher run [is allowed|https://github.com/apache/camel/blob/camel-2.21.1/components/camel-consul/src/main/java/org/apache/camel/component/consul/endpoint/AbstractConsulConsumer.java#L95]. Thus _EventWatcher.watch_ is called with uninitialized _scheduledExecutorService_ and failing with NPE.
