I am testing apache karaf 4.1.0-SNAPSHOT, which in turn uses pax-web 4.4.0.

After starting the feature http-whiteboard and then try to add a servlet, I get the following warnings in the log file (data/log/karaf.log). However, according to the log, the JSR 356 WebSocketServerContainerInitializer should have beed added successfully.

Although this is a WARN instead ERROR message, an application user cannot evaluate the consequence. Thus, in my opinion, this warning should be either fixed or logged in level INFO.

Best regards

Lijun Liao

Hi Lijun,

yes, this should be handled better, could you please open an Issue about it.

If you don't have an account yet, let me know and I'll create one for you.
