I can change the last sentence in the 1st par in this section to be either:
During the processing of the close() method, the embeddable container must cancel all pending asynchronous invocations and call the PreDestroy methods of any singleton session bean instances in the application.
During the processing of the close() method, the embeddable container performs the following steps:
* cancels all pending asynchronous invocations
* calls the PreDestroy methods of any singleton session bean instances in the application
* aborts execution of bean methods that are still active
My concern with the last bullet in the option (B) (or adding something similar to (A)) is that it's not clear that PreDestroy methods will be allowed to complete.
Let me know what you prefer.

I think that now that async is supported for Embeddable container we should add the change on the section.

Well, would expect the same behavior you discribe for GlassFish
: the execution is aborted when the server shutsdown (I don't
want the embedded container to get locked while a thread is
trying to finish its processing).

What do your think? How do you expect your embedded
containers handle the async calls during EJBContainer.close
and JVM exit?
GlassFish (RI) uses the same code for embedded and regular
shutdown, where the bean is unloaded right away, and any
method execution is pretty much aborted when the server
shutdown event is received. JVM exit is intercepted and
EJBContainer.close() steps are executed in the background.

(EJB_SPEC-57) Define asynchronous thread behavior upon close
of embeddable container

jrbauer commented on EJB_SPEC-57:
Section 18.2.4 (pd1) does contain some verbiage around
shutdown requirements and expectations of the embeddable
container. I shied away mentioning any sort of asynch
shutdown expectations for containers in an EE environment
since I too couldn't find anything around this topic in the
specs. Introducing something now would likely cause
compatibility issues for most vendors. But, since asynch
support will be new in the embeddable container we have an
opportunity to introduce some commonality/predictability
without release compatibility concerns.
Define asynchronous thread behavior upon close of
Issue Type: Improvement
Affects Versions: 3.2
Issue EJB_SPEC-13 adds asynchronous method invocation to
EJB lite, which may be implemented by an embeddable
container. The specification should define the behavior
of the embeddable container regarding any outstanding
asynchronous invocations upon closing the container
(EJBContainer.close()) and since close() is not required,
exit of main within the JVM.
Transactionally, it seems to make the most sense for
EJBContainer.close() and JVM exit to wait for any
outstanding asynchronous threads before exiting. This
provides consistent behavior, but at the risk of having
an ill-behaved thread block the container or JVM from
