----------------------------------------

Thanks
To my sorrow i can not test it in WL10 now, because of shortage of time. 
The solution from Link works in Wildfly 9.0.1.Final: quorum 1. The difference is only that Function "PrefferedNode" doesn't work and Stop/new Start of Singletone in Node1 (or Node2) is not called during down of other Node2(or Node1) - Singleton doesn't Start everything again in case of down of another Node. If Singleton was in Node that is down than it will be started in other Node.

Is there any Description of methods at all? Despite of Examples in GitHub -some background was-is absent.

Will be old solutions supported in new versions of WF?
