Could not read manifest information. /dev/shm/Log4jHotPatch.jar

Hey folks,

I’m seeing the following line in my Tomcat docker container logs. The application is using Scala/Scalatra/Akka.

[] WARN a.u.ManifestInfo - Could not read manifest information. /dev/shm/Log4jHotPatch.jar (No such file or directory)

Interestingly, there is no such message when I run the application on a Tomcat server outside Docker. Is this related to Akka or should I worry (the message is generated here)? Is there an easy mean to get rid of it?

You could silence the akka.util.ManifestInfo in your logging config. It’s a caught exception and should be harmless, and the logger is not used for anything else than that specific warning.
