Exception on implementing HttpSessionListener in Gosu. gw.internal.gosu.parser.JavaType_Proxy cannot be cast to gw.entity.ITypeList

[Varghese Renny]

Hi I am getting below exception on configuring servlet listener in GW. This is done to redirect to some logout page on session termination. Below are the changes done.

It's is running on jetty server.

web.xml

<listener>
 <listener-class>eic.integration.authentication.filter.EICHttpSessionListenerCSRF</listener-class>
</listener>

EICHttpSessionListenerCSRF.gs

class EICHttpSessionListenerCSRF implements HttpSessionListener {


 override function sessionCreated(httpSessionEvent: HttpSessionEvent) {
 print("CSRF Session Creation "+httpSessionEvent.Session.CreationTime)
 }

 override function sessionDestroyed(httpSessionEvent: HttpSessionEvent) {
 print("CSRF Session Destroyed "+httpSessionEvent.Session.LastAccessedTime)
 }
}


I am not sure why this exception getting thrown? Please help.
