One thing to note here is that there are two spans that track the flow of sink message on the consumer side.   One span is around dispatch on the sink consumer  and another is child span around  flows persisting to elastic search.  For OpenNMS case, the span around elastic search is not resulting as child span as  ElasticFlowRepository is a bundle and uses a different class loader for initializing tracer than the  DispatcherFactory which is on default class loader.    This works fine on Sentinel where everything is on  karaf.
