Description
When Tests are executed massivley multithreaded, from time to time a ConcurrentModificationException is thrown when JBehave tries to write a report-file.
Trace:

@Mauro: I am currently running 3.8, but I reproduced this Problem with all 3.x Versions i tried (3.69, 3.8, 3.9.x)
I am sorry, I can not provide a Project easily, as it is company property, but I could provide snippets if you tell me what you need.
As a follow up to this Problem, the Jenkins build fails because there are errors processing the result file. The Jbehave-Jenkins Plugin seems Buggy as well, as i cannot remove the check-flag from the "Stop and set the build to 'failed' status if there are errors when processing a result file"-Option (I can actually remove it, but the setting is not saved and is checked again next time i open the job).

made changes -
| Field | Original Value | New Value |
|---|---|---|
| Priority | Critical [ 2 ] | Major [ 3 ] |
As a workaround I changed my code to write reports at the very end where no concurrency issues appear. Because of this I also changed the priority of this Issue from "Critical" to "Major":
new CrossReference().withOutputAfterEachStory(true);
to
new CrossReference().withOutputAfterEachStory(false);

Which version are you using? Can you provide a sample project that reproduces this behaviour?
