Eduardo Martins commented on WFLY-13051:
----------------------------------------

[~nimo22] That shouldn't happen, the recurrent task should be cancelled, can you please re-check that and if that happens submit a new bug JIRA and attach an app project or WFLY integration test that I may use to recreate the issue?

> {code}
> throws the error:
