    @joewitt  - Perhaps you would you be able to give me some insight here.
    
    For some reason when I run the following lines of testOutgoingMessageAttachment
    
    ```
            extractAttachmentsRunner.enqueue(message);
            extractAttachmentsRunner.run();
    ```
    
     I hit the following error message:
    
    ```
    [pool-5-thread-1] ERROR org.apache.nifi.processors.email.ExtractEmailAttachments - ExtractEmailAttachments[id=a209646b-88f5-4a59-bafb-7aba063ed481] Could not parse the flowfile FlowFile[0,632793727136184.mockFlowFile,917B] as an email, treating as failure: java.lang.IllegalStateException: FlowFile[0,632793806568613.mockFlowFile,0B] already in use for an active callback or InputStream created by ProcessSession.read(FlowFile) has not been closed

    ```
    
    Not sure if this is a bug on ExtractEmailHeaders / ExtractEmailAttachments or if it is a mistake within the test script itself?
    
    Cheers
