--------------------------------
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:
