This occurs when the server is sufficiently fast during startup. Though its disconcerting for sysadmins to see the exception, the race condition has no further side-effects.

Pushing to milestone:3.0-Beta4 to not make any large-scale changes this close to release.

This issue has not reappeared after some larger reworkings of the spring configurations. Closing.
