Description
At the moment StalePageException doesn't call 'super("Some message")' and also doesn't fill its stack trace (this is intentional!) and when logged it appears in the log as:
Exception occurred:
org.apache.wicket.core.request.mapper.StalePageException: null
which is not very informative.
It would be better to set a message that provides some information about the page, like page.toString().
