Hi Achim, thank you for the super-quick feedback. I'm sorry, I didn't know that it is mandatory to propagate log events to the event-admin service... I thought it could reasonably be a configuration option, since not everybody needs that for the business logic, but I guess it is needed by the underlying runtime implementation (Apache Karaf, in my case).
Do you think that filtering at the event-admin level will be equally efficient, in terms of not congestioning the threadpools?
