It happens when i restart tomcat and tomcat deserializes sessions.
If it doesn't deserializes sessions it doesn't happen.
Will try if i can really reproduce it and see if i can figure out why ..
The big problem is that noclassdeffound is the most most annoying and don't
tell what really is the problem error. I hate hate hate that error.

Hi,
today I tried to use my own class MyReasourceStreamLocator based on
AbstractResourceStreamLocator and registered it in Application.init()
(the derived method).
Surprisingly, I got a "NoClassDefFoundError". A part of the stack trace
is shown below. I am using Wicket 1.2beta2.
java.lang.NoClassDefFoundError
java.lang.Class.forName0(Native Method)
java.lang.Class.forName(Class.java:164)
wicket.markup.html.tree.TreeComponentInitializer.class$ (TreeComponentInitializer.java:38)

wicket.Application.initializeComponents(Application.java:693)
wicket.protocol.http.WicketServlet.init(WicketServlet.java :287)
Line 38 in the source file TreeComponentInitializer.java is the first
line inside this method:
public void init(Application application)
{
PackageResource.bind(application, Tree.class, " blank.gif"); //line #38
PackageResource.bind(application, Tree.class, "minus.gif");
PackageResource.bind(application, Tree.class, "plus.gif");
PackageResource.bind(application, Tree.class , "tree.css");
}
Could it be a problem that Tree is an abstract class?
