Getting Exception org.apache.logging.slf4j.SLF4JLoggerContext cannot be cast to org.apache.logging.log4j.core.LoggerContext

Remove below jar’s from class path and it should fix the issue –

log4j-to-slf4j-2.0.2.jar
log4j-to-slf4j-2.0.2-sources.jar
log4j-slf4j-impl-2.0.2.jar
log4j-slf4j-impl-2.0.2-sources.jar

I was able to replicate and fix the issue after downloading
apache-log4j-2.0.2 from
http://www.apache.org/dyn/closer.cgi/logging/log4j/2.0.2/apache-log4j-2.0.2-bin.zip.
