Hi,
I am also hitting the same ClassCastException issue while trying to run the log4j2 in WebLogic application server. Here is what I have done:
- if I put the api and core jars into DOMAIN_HOME/lib (equivalent to adding the jars into server classpath) things run okay.
- if I put the api and core jars into WL_HOME/server/lib/mbeantypes/3rdpartyjars, then this classcast exception is thrown:

System.out.println("\tAppenders:" + mp.keySet());

===============ends==================
- with least hope to solve this issue, I also merged the two jars carefully (making sure MANIFEST.MF has all the entries) into single one but still same issue.
Hope this helps in someway to identify what is going wrong.
I am ready to test to collect any additional data for debugging.
Thanks
