Apologies for having asked such simple question, I have only some experience with embedded Java...
I have added the
<dependency>
<groupId>org.eclipse.jetty</groupId>
<artifactId>jetty-slf4j-impl</artifactId>
<version>${jetty.version}</version>
</dependency>
to the pom.xml and now my WAR servlet finally works well with Jetty 10.0.6.
Does it make any sense to add "servlet" module, when I already have "deploy" module added?
I have tried with and without "--add-module=servlet" and could not see any difference.
Also, I am curious that when I compile my WAR file against Jetty 10.0.6 and then put it into webapps dir of the old Jetty 9.4.x installation on my Linux server, then it fails with:

Shouldn't the WAR file have some standard APIs and thus run fine in both deployments, Jetty 10 and Jetty 9?
Best regards
Alex
