A couple of new features have been added that should help you: 1. Log4j now supports a PatternSelector so you can have multiple patterns specified for an appender. 2. A new unreleased feature (it will be in 2.5) is the ability to using Scripting on the PatternSelector. With that you can write a script and if the LogEvent contains an exception then you would choose the Pattern that includes the MDC information.
