-------------------------------------------------------------
The error message suggests that you have a cache listener that implements
ICacheListener where it should rather implement IRemoteCacheListener.
It is not a good sign when this warning occurs because it actually shows that
something is wrong in the implementation. Watch for the warning "Dropping Event
and marking Event Queue \{0\} as non-functional."
Please double-check your code.
Other than that, JCS actually uses java.util.logging by default. If you did not
call JCS.setLogSystem(LogManager.LOGSYSTEM_LOG4J2) before JCS.getInstance(...),
your log4j-configuration will not take effect.
For disabling warnings for the logger LogManager.getLog(
AbstractCacheEventQueue.class ), see the documentation of your log system.
