Brian Stansberry commented on WFLY-6895:
----------------------------------------

The linked PR is for the 10.x branch and it looks fine for that, so assuming it still passes CI I'll merge it. There are no particular plans for another 10.x release though.

For WF 11, WFCORE-1272 has fixed the problem.

> I found a problem with TimerService that occurs when your application is configured as a singleton deployment.
> *Test Case*
> # Start master node, the app is also started - OK
> # Start slave node, the app is deployed but bot stared - OK
> # Stop master node, the app is started on slave - OK
> # Start master node, there is a preference for node name so the app will be started again on master and stopped in slave - OK
> # Stop master node, the app should be started again on slave but an exception occur. - ERROR
