Instrumentations that use custom
StartTimeExtractor&EndTimeExtractorwill have completely wrong duration metrics, sinceRequestListenerimplementations tended to get the time usingSystem.nanoTime()without taking the custom times into account.Currently it's just JMS & Kafka instrumentations that use custom time extractors and they do not have any metrics at all - but once we introduce messaging metrics it'll become a problem. (Also, the Armeria instrumentation might make use of those custom extractors; the tracer-using instrumentation certainly did)
