> {{OnWindowsExpirationContext}} can not be used as a parameter for {{DoFn}} methods annotated by {{@OnWindowExpiration}}. The following exception is raised:
> {code:java}
>  java.lang.IllegalArgumentException: org.opennms.nephron.cortex.PaneAccumulator$PaneCombinerFn: Illegal parameter type: OnWindowExpirationContextParameter{}{code}
> As a workaround a parameter of type {{OutputReceiver}} can be used, though.
