      During reload of server it can happen that following ERROR is logged:

      Expectation is that no WARN/ERROR logs will occur during reload. Besides the error log the issue appears to be harmless.

      Test scenario:
      Start server in standalone-full-ha.xml profile and reload 100 times. Always wait for the EAP server to get to running state before reloading the server again.

      Pass Criteria: Check there are no exceptions from :reload operation calls.

      Customer impact: Customers utilizing log monitoring will get "false alarm" during reloading of the server. This issue affects user experience.
