Another wicket user! I'm down to about 2-3 seconds for the WicketFilter init(), which includes the Application init(). Since I figure I'm only allowed about 2-3 seconds, I realized that it was either give up Wicket or give up JDO. So, I swapped out JDO for Objectify and couldn't be happier. You may want to look into that. Objectify can also use the MemCache if you're getting by key, which (I believe) means that multiple instance restarts will be able to use the same cached data for speedier recovery.
I don't want to hijack this thread, but if you have a moment, I'd love for you to take a look one of my Wicket/GAE issues at http://apache-wicket.1842946.n4.nabble.com/GAE-loses-shared-resources-td1883638.html to see if you have any advice.
