Choose the correct answer:

What happens when an exception is raised by an Action within an Activity that has been invoked asynchronously?

Show Suggested Answer Hide Answer
Suggested Answer: D

For asynchronous invocations in UML, when an exception is thrown and there is no matching exception handler within the activity, the exception is effectively lost because there is no direct mechanism to propagate it back to the caller. This reflects the nature of asynchronous communication where the calling process does not wait for the completion of the called process and, thus, may not be designed to handle exceptions that occur during the called process.


UML 2.5 Specification: The UML specification describes the behavior of actions within activities and how exceptions are handled, or not handled, in the case of asynchronous calls. It specifically states that for asynchronous calls, the exception is not propagated back to the caller as there is no return flow defined for such invocations.

I think C) The catching exception handler has exactly one output pin makes sense, as it helps in handling the exception within the Activity.

I'm not sure, but I think D) The exception is lost if there is no matching handler within the Activity.

I agree with France, because when an exception is raised, it should be passed back to the caller.

Hmm, I'm not sure, but C seems a bit too specific. I'll have to go with A or D.

B can't be right, exceptions can definitely be handled in an asynchronous context. I'd go with A.

D seems like the right choice. If there's no matching handler within the Activity, the exception would be lost, right?
