We are implementing the fan-out/fan-in pattern in our use case. In this pattern, If one of the activity function fails, we need to identify the specific function that encountered the error, in the orchestrator function.

Consider the following code block as an example:
List<Integer> results = ctx.allOf(parallelTasks).await();

In the event of a failure in any of the activity functions, the results variable remains unpopulated. This means that even if some activity functions have completed successfully, we are unable to distinguish them.

Is there a way to address this issue and accurately identify the successful activity functions?
