Issue with log4j 2.17.0 update: ClassNotFoundException SetUtils

Issue

After the version bump to log4j 2.17.0 this exception was raised during the unit tests:

java.lang.ClassNotFoundException: org.apache.logging.log4j.core.util.SetUtils

How to work around this problem?

Solution

After some trial and error I found here that upgrading to log4j 2.17.0 implies a new dependency log4j-web

<!-- https://mvnrepository.com/artifact/org.apache.logging.log4j/log4j-web -->
<dependency>
    <groupId>org.apache.logging.log4j</groupId>
    <artifactId>log4j-web</artifactId>
    <version>2.17.0</version>
</dependency>
