Bug#1034855: trapperkeeper-webserver-jetty9-clojure: autopkgtest regression: Cannot invoke "Object.toString()" because "s" is null

[Jérôme Charaoui]

This problem is caused by a recent patch shipped by the liblogback-java 
package, specifically this line, which causes log events to be silently 
ignored:

https://salsa.debian.org/java-team/logback/-/blob/master/debian/patches/tomcat10-migration.patch#L91
See the discussion in 
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=1036250

In my view this is a bug in src:logback.
