Affects Version/s: 3.5.0 GA (4.8.0 GA Suite Release)
Fix Version/s: Backlog
`mondrian.server.Execution.copyMDC(Execution.java:113)` uses `org.apache.log4j.MDC.getContext()Ljava/util/Hashtable` which is not part of the public log4j API.
- Get the current thread's MDC as a hashtable. This method is
- intended to be used internally.
This breaks compatibility with log4j-over-slf4j and ch.qos.logback.log4j-bridge. It would be great if it could be implemented another way.
