When shutting down confluence gracefully, it will emit a whole slew of runtime exceptions, due to the plugin system trying to emit events after the cache manager is stopped. Confluence will emit one of these stack traces per module descriptor that was enabled, and one per plugin that was enabled.

Addtionally, logging itself seems to get disabled before we stop trying to use it:
2010-12-02 14:03:20,765 INFO [main] [com.atlassian.confluence.lifecycle] contextDestroyed Stopping Confluence
log4j:ERROR LogMananger.repositorySelector was null likely due to error in class reloading, using NOPLoggerRepository.
Neither of these should be happening: it means our shutdown sequence needs to be tidied up.
