I asked the opentelemetry-java developers [5] and we can try and set the handler multiple times, but only the first one will be used. I suspect they need these for handling Servlet includes, so this fits our use case perfectly. So no need to change stuff in Sling :-) Thanks, Robert [5]: https://github.com/open-telemetry/opentelemetry-java-instrumentation/discussions/9384
