The org.apache.logging.log4j:log4j-api library gets converted because it has some hard-coded references to javax.servlet.Servlet and javax.xml.bind.DataTypeConverter.

In org.apache.logging.log4j.util.Constants there is lookup for both javax.servlet.Servlet and jakarta.servlet.Servlet so there is no need for the conversion there.

In org.apache.logging.log4j.util.Base64Util there is a lookup for javax.xml.bind.DataTypeConverter. This is only if java.util.Base64 is not available. This is available in Java 8 so there is no need for the conversion here either.
