> Issue Type: Bug
> Components: wicket
> Affects Versions: 1.4-RC2
> Reporter: Adriano dos Santos Fernandes

> I start Jetty with a savePeriod (HashSessionManager) of 4 seconds. When I restart it, a NPE is logged each 4s. After some (not all) page loads, the exception stop.
> Since NPE is never a feature, I suggest to apply that patch. Or something else more appropriate, if you understand the problem better.
