The existing shutdown hooks already provide lots of rope to hang 
yourself and so I think any proposal to expose priorities in the API 
would need to be approached with great care. As you have found, the JDK 
internally can run hooks before or after the application hooks but given 
the delicate time when they run then great care also needs to be taken 
when doing any adjustments there too.

In any case, the LogManager shutdown hook does need to be looked at as 
it clearly has a number of issues.
