      Description

      Some Controller Services take a while to enable. And if a Controller Service fails to enable, it will remain in an ENABLING state while it retries. This can take an indeterminate amount of time.

      If a parameter context is updated while a service has a state of ENABLING, and the Controller Service references one of the the affected parameters, the update will fail with the following stack trace in nifi-app.log:

      2021-06-08 10:52:55,738 ERROR [Parameter Context Update Thread-1] o.a.n.web.api.ParameterContextResource Failed to update Parameter Context
      java.lang.IllegalStateException: Cannot update Parameter Context testParamChangeWhileReferencingControllerServiceEnabling because it has Parameters that are being referenced by a Controller Service that is enabled.
