> h3. *Description*
> After upgrading to {*}JUnit 5{*}, the {{ResourceManager}} module encounters a
> crash when running unit tests. Specifically, the failure occurs in the test
> case {{{}TestAppManager#testRMAppSubmitWithQueueChanged{}}}.
> During application submission, the test changes the queue assignment, which
> triggers a {{SchedulerEvent}} that the {{AsyncDispatcher}} cannot handle.
> As a result, the dispatcher thread throws an exception and terminates,
> causing the test JVM to exit abnormally with a
> {{{}SurefireBooterForkException{}}}.
> *Error Details*
> {code:java}
