ERROR WFLYCTL0013 and WFLYCTL0216 logged when accessing /metrics endpoint after disabling or undeploying an application in JBoss EAP 7.x

Issue

• When an application is disabled or undeployed in JBoss EAP 7.4, repeated ERROR messages are logged in server.log each time the metrics endpoint (/metrics) is accessed.

• The following error is observed in the logs:

  ERROR [org.jboss.as.controller.management-operation] (management I/O-2) WFLYCTL0013: Operation ("read-attribute") failed - address: ([
      ("subsystem" => "infinispan"),
      ("cache-container" => "web"),
      ("cache" => "application_name.war")
  ]) - failure description: "WFLYCTL0216: Management resource '[
      (\"subsystem\" => \"infinispan\"),
      (\"cache-container\" => \"web\"),
      (\"cache\" => \"application_name.war\")
  ]' not found"
  

• This error occurs only when metrics are being collected (e.g., via http://localhost:9990/metrics).

• The issue does not impact the actual availability of the application server or other running applications.
