    Description

      The WhitelistedClassesResourceGuard class is not thread-safe, yet a single instance of it is used by Wicket in (possibly) multiple concurrent threads.

      As a result, access to resources may occasionally be denied because the list of whitelisted prefixes is not properly initialized yet. One example we've seen is a failing call for the background image of the console application.
