Is there a way to pool JarFile instances so we reuse the same one every
second instead of creating a new one? Also, maybe we can create our own
UrlClassLoader (copy Sun's and add a closing mechanism which Wicket
would use)?

No this is already discussed long time ago on this mailing list.
It is a bug of sun. We can't do ONE thing about it.. It really sucks i
know but its out of our hands.
Here is the bug: http://bugs.sun.com/bugdatabase/view_bug.do?bug_id=4950148
Please vote for it, because we as wicket really have problems with it
because we have many resources.
Maybe we can make the polling smarter.. If the resources comes from a
jar file then don't test it anymore.
But don't know if we can see that (its the instance of the url
connection that specifies that i guess)

Eek, XML files! ;)
That aside, I assume this means there is a bug in resource
polling? ...
or is it normal for it to open all these files and never close them?
