[jboss-jira] [JBoss JIRA] (WFLY-8184) Singleton deployment not stopped on the previous singleton provider after new provider is elected

Singleton deployment not stopped on the previous singleton provider after new provider is elected ------------------------------------------------------------------------------------------------- Key: WFLY-8184 URL: https://issues.jboss.org/browse/WFLY-8184 Project: WildFly Issue Type: Bug Components: Clustering Reporter: Radoslav Husar Assignee: Radoslav Husar Priority: Critical Scenario: failover clustering test with singleton deployment. {code:xml|title=Singleton subsystem configuration} <subsystem xmlns="urn:jboss:domain:singleton:1.0"> <singleton-policies default="default"> <singleton-policy name="default" cache-container="server"> <random-election-policy/> </singleton-policy> </singleton-policies> </subsystem> {code} Nodes startup order: node1, node2, node3, node4. During node1 startup, this server is elected as the singleton provider and deploys singleton deployment. During other servers startup, some other node (usually node2) is elected as the singleton provider and deploys singleton deployment. However, node1 has the singleton deployment still deployed, so there are *2 nodes* effectively providing a singleton deployment.
