-----------------------------------

             Summary: Adding behavior in component instantiation listener causes Page.onInitialize() being called even if constructor throws an exception
                 Key: WICKET-5546
                 URL: https://issues.apache.org/jira/browse/WICKET-5546
             Project: Wicket
          Issue Type: Bug
          Components: wicket
    Affects Versions: 6.14.0, 6.13.0
            Reporter: Robin Shine
            Priority: Minor


Page.onInitialize() will be called even if constructor throws an exception
in case below code is added in wicket WebApplication.init():
getComponentInstantiationListeners().add(new IComponentInstantiationListener() {
              @Override
              public void onInstantiation(Component component) {
                  component.add(new Behavior() {

                  });
              }
             
          });

It seems that the instantiation listener adds the behavior to the page at very start of the page constructor, and then the page is marked as dirty to cause onInitialize() being called afterwards.
