Bonjour Jean-Baptiste,

This is not running under Karaf, just running as a standard PDE OSGi 
project and it is using Pax Web (7.2..21) with Jetty (9.4.36)

Here's a small snippet of the log, with some failed, 1 success and 1 
skipped.
09:18:11.955  [paxweb-config-1-thread-1] ::: INFO  
o.o.p.w.u.ServletContainerInitializerScanner - will add 
ch.qos.logback.classic.servlet.LogbackServletContainerInitializer to 
ServletContainerInitializers
09:18:11.957  [paxweb-config-1-thread-1] ::: WARN  
o.o.p.w.u.ServletContainerInitializerScanner - failed to parse and 
instantiate of javax.servlet.ServletContainerInitializer in classpath

Let me know if I can provide more detailed information or perform 
additional debugging.
