"cancelled task by interrupting thread Thread" is emitted without any reason

When I was performing Spring Session and Kubernetes Rolling Update demo I encountered a couple of problems.

One of the is this:

[transactions-repository-1-2sn4z] 18:21:20,548 INFO  [org.jboss.as.protocol] (management task-9) WFLYPRT0057:  cancelled task by interrupting thread Thread[management-handler-thread - 2,5,management-handler-thread]

The event seems to be emitted on steady cluster state without any reason.

Full logs from Rolling Update process might be found here: https://gist.github.com/slaskawi/530241bb695f1f490bcb25eabaf9d676

Steps to reproduce:

• Start local OpenShift Cluster
• invoke `./init_infrastructure.sh` from https://github.com/slaskawi/presentations/tree/ISPN-7487-reproducer
• invoke `cd transaction-creator && mvn fabric8:run`
• Do the rolling update: `oc deploy transactions-repository --latest -n myproject`
• Observe logs `kubetail -l environment=infrastructure`
