David Lloyd commented on JBREM-1080:
------------------------------------

I guess a simpler solution would be to just put a finalize method on RequestContext.  It would be a shame to lose the ability to know immediately if a response was not sent but I guess that's OK since it represents a programming error, not something that should normally happen.

> Right now, the RequestContext keeps track of tasks and threads being used to process a request.  If all tasks complete and no reply is sent, it makes sure that the requesting party receives an exception indicating that a reply was never sent.  However, if the request listener may wish interact with another framework which uses some asynchronous callback mechanism, from which a reply is to be sent.  In this case, all tasks terminate but the reply might still be sent.
> To solve this problem, RequestContext needs a method which can wrap a Runnable (or similar) with some type of cancellable Runnable or task object, which can then be called by other frameworks as needed later on.  The RequestContext wouldn't consider a request "dead" until all tasks completed and all such wrapped Runnables have also been completed or GC'd.
