Gary, enjoy your holiday! Mikael, At first glance it seems to me that this problem happens because the application does not start logging until it has done all the work and the JVM is shutting down.
However, I'm not sure it really is a problem: Log4j tried to registered a shutdown hook, but couldn't. It then notified you of the problem and continued to work. (The stack trace was generated from a try/catch block.) If this error report is annoying, a workaround may be to change to your app to start logging at startup.
