We have migrated to OpenTelemetry because RHBQ 2.13 release notes pointed out that smallrye opentracing was deprecated.
But we spotted that in one of our usecase a regression compared to the usage of smallrye-opentracing which is the following : 

The OTEL context is not propagated when we use our own ExecutorService but instrumented with ThreadContext propagation.

We created a reproducer available on github ( https://github.com/OpenGuidou/opentelemetry-propagation-reproducer) that is showing that we loose the traceid upon creating a new span in an asynchronous method execution, whereas quarkus bootstraps should ensure the propagation.

This case is quite urgent because it blocks us towards the migration to newest RHBQ (2.13)
