call hierarchy for annotations ?

We have an own event system in our Java project working on an jboss server.

so we can make calls via the following syntax:

send a call within an EJB Method

eventSender.send(EventConstants.EVENT_printDocPost, contract);

now all right annotated Methods runs:

@OnEvent(eventname = EventConstants.EVENT_printDocPost)
public void EVENT_printDocPost(contractOrm contract) throws KwsdException {

     ...

}

Is there a possibility to add this flow to the call hierarchy ?

Maybe i can write a intellij plugin or so, which are the api methods i should/can use ? are there similar plugins ?
