Could we verify this, so the docs can be updated properly?

When setting up rollbar-log4j java integration in a project which builds a fat-jar, additional configuration is needed, which is not mentioned in the docs or example. As rollbar-log4j contains additional .dat files, these must to be concatenated with the other log4j files.

This can be achieved using this gradle lib https://github.com/TheBoegl/shadow-log4j-transformer
This is the maven equivalent: https://github.com/edwgiz/maven-shaded-log4j-transformer (however, I only used the gradle solution so far)

This issue contains additional information, the logged error, as well as the links to the libraries https://issues.apache.org/jira/browse/LOG4J2-954 Might be worth adding this to the rollbar doc, as the logged error is a little misleading.
