Hi,
Wicket catches all runtime exceptions and gives them to all configured
IRequestCycleListeners (#onException()). If none of them knows how to
process the exception then the exception is given to IExceptionMapper (see
Application#newExceptionMapper). The default impl of this mapper is to show
the configured IApplicationSettings#getInternalErrorPage().
As a final resort you can provide your own IExceptionMapper that re-throws
OAuth2AccessTokenRequiredExcep**tion.
