Commit e362ee077fb4c86fcadab6ca951d70d37b1b02b6 in nifi's branch
refs/heads/support/nifi-1.19 from Mark Payne
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=e362ee077f ]
NIFI-10937, NIFI-10938, NIFI-10939: When restoring flow from XML, properly
parse XML for registry clients, looking for 'id' tag instead of 'identifier'
tag. Fixed typo in error message about Reporting Task for Registry Clients.
Updated StandardFlowComparator so that we compare sub-process groups' contents
only if the Flow Coordinates are different by more than their version
Signed-off-by: Nathan Gough <[email protected]>
This closes #6752.
> If Registry Client exists in flow, NiFi will fail to startup from flow.xml.gz

> If there exists a flow and a Registry Client has been added, upon restart
> everything loads properly from the flow.json.gz. But if for any reason we
> attempt to load from flow.xml.gz (because flow.json.gz was removed), NiFi
> will fail to startup with a NullPointerException:
