Well, seems this first part was not hard at all.
I've attached a patch on https://issues.apache.org/jira/browse/OPENEJB-1165
Included the AsynchronousRunner and AsynchronousRunnerTest.
That's great! All committed!
We'll need to get those Thread.sleeps out of there. There are some
cool java.util.concurrent classes we can which are actually easier
once you get the hang of them. The one I use most for testing
multithreaded code is java.util.concurrent.CountDownLatch.
In your test case you could construct a "CountDownLatch latch = new
CountDownLatch(1)" and pass that instance to your asynchronous method
so both the test case and the target method have a reference to the
same latch. The method will just call latch.await() which will cause
the asynch thread to pause. Then in your test case you can test the
'isDone' logic on your future, then call latch.countDown() which will
cause the asynch thread to resume and complete, then you can test your
'isDone' 'true' logic. Best to call get() on the future before
calling isDone() or isDone() could return false.
Aside from the test case, the next step is updating the descriptor
reading code[1] so that it can handle the new async method related ejb-
jar.xml syntax [2].

SessionBean.java
2. http://java.sun.com/xml/ns/javaee/ejb-jar_3_1.xsd
There's a test case[3] that reads in a sample ejb-jar.xml file[4]. It
should be fairly easy to update the ejb-jar.xml file to have a few of
the new async elements so that you can verify the reading/writing
works fine.
