I've been spending some time today trying to figure out what's causing this (cf #1362) and honestly I'm not sure, but it seems like various pieces of instrumentation aren't working... Especially in scala 2.13. Scala 3 doesn't seem to have any issues.. so that's odd. Would rather the instrumentation tests passed for pekko 1.1, because otherwise we're probably hiding errors... |

@hughsimpson feel free to do a new PR that sorts out the instrumentation issue. This PR is useful as far as I am concerned because it stops Kamon from crashing the JVM. To repeat what I said in the PR description: |

relates to #1352
unit tests pass and tested with https://github.com/pjfanning/kamon-pekko-http-test
The NPE may pop up in other use cases but this sorts the one seen in #1352
I know a fuller fix is needed - one that ensures the dispatcherPrerequisites are found but that can be done independently.
