--------------------------------

             Summary: When updating Parameter Context, sometimes see failure: processor cannot be started because it is not stopped. Current state is STOPPING
                 Key: NIFI-8731
                 URL: https://issues.apache.org/jira/browse/NIFI-8731
             Project: Apache NiFi
          Issue Type: Bug
            Reporter: Mark Payne
            Assignee: Mark Payne


To replicate:
 * Create a Process Group with a Parameter Context bound
 * Create a Processor that references a Parameter
 * Start the Processor
 * Change Parameter to a value that will make the processor invalid
 * Attempt to change the Parameter again

This will result in a stack trace similar to:
{code:java}
