>
> The testcase testCoordActionInputCheckXCommandUniqueness is unstable.
> We add three XCommands with the same actionId (entityKeys are different) into
> the CallableQueueService. Only the first XCommand is expected to run.
> The reason why sometimes either the 2nd or 3rd XCommand executes is because
> as soon as the first starts to run, its removed from the {{uniqueCallables}}
> map immediately. If the first scheduled task runs quickly, then either the
> 2nd or 3rd XCommand has the chance to get scheduled.
> Step by step:
> 1. Schedule first XCommand
> 2. XCommand is added to {{uniqueCallables}}
> 3. Schedule second XCommand
> 4. First XCommand starts to run in the thread pool and removes itself from
> {{uniqueCallables}} (see {{CallableWrapper.run()}})
> 5. Second XCommand can successfully add itself to {{uniqueCallables}}
> 6. Second XCommand starts to run
> Please clarify whether this is the expected behavior of CallableQueueService.
> If not, then moving {{removeFromUniqueCallables()}} to the finally block
> solves the problem.
