Failed to load SumoLogicAppender when the app is a fat jar

[liangde-chen]

It works if I start the app from IDE, but if I build the app into a fat jar and run it, it doesn't work.
I can confirm the com.sumologic.log4j.SumoLogicAppender.class is included in the fat jar.

It got this error ERROR Error processing element SumoLogicAppender ([Appenders: null]): CLASS_NOT_FOUND

Close it since it is a log4j2 implementation bug: https://issues.apache.org/jira/browse/LOG4J2-673

OK, so this is a log4j2 bug, but does this mean I can't use a SumoLogic appender in a fat jar file with Log4J2? Is there a work around? Are there alternatives?
