[jira] [Created] (NIFI-4718) IdentifyMimeType: increase priority for FFv3

Brandon DeVries created NIFI-4718:
-------------------------------------

             Summary: IdentifyMimeType: increase priority for FFv3
                 Key: NIFI-4718
                 URL: https://issues.apache.org/jira/browse/NIFI-4718
             Project: Apache NiFi
          Issue Type: Bug
          Components: Extensions
            Reporter: Brandon DeVries
            Priority: Minor


IdentifyMimeType uses tika configured with a custom-mimetypes.xml\[1] to specify (among others) the flowfile-v* mime types.  However, these do not include priorities.  Therefore, a NiFi FlowFile V3 package with a payload containing, for example, html including the string:
{code}
<html xmlns=
{code}
will be identified as "application/xhtml+xml" \[2] which, while matching the pattern, is not as correct as identifying it as application/flowfile-v3.  To fix this, I believe we need to specify a higher priority for the FlowFile V3 "magic"...
