             Summary: Exception coming from FlowFileQueueSize
                 Key: NIFI-1110
                 URL: https://issues.apache.org/jira/browse/NIFI-1110
             Project: Apache NiFi
          Issue Type: Bug
          Components: Core Framework
            Reporter: Bryan Bende


I was using the latest build of master on a CentOS 7 VM. I had a flow with several processors and one of them stopped with a few flow files queued in front. I then stopped the preceding processor and changed the expiration time on the queue, then started the processors and got the following exception in the logs:

Reproduced this fairly easily on the CentOS VM, but had trouble reproducing on my macbook.
