Recently upgraded from jboss-as-7.1.1.Final to wildfly20. We have agent CA Wily Introscope(R) Version 10.5.2 Release 10.5.2.15 installed which was just working fine with Jboss 7. After the Wildfly20 upgrade, we are getting the below error. If I disable the agent then these errors go away.
The highest release supported on all Agents is Wildfly 11. So Wildfly 20 is not supported at this time on any agent. Please open a case to have Support submit a compatibility Guide Request.
