[jira] [Commented] (NIFI-10937) If Registry Client exists in flow, NiFi will fail to startup from flow.xml.gz
[ https://issues.apache.org/jira/browse/NIFI-10937?page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel&focusedCommentId=17642727#comment-17642727 ]
ASF subversion and git services commented on NIFI-10937:
--------------------------------------------------------
Commit e1c8c9611118c6634160dfe0dad3f6f6c6b56b4d in nifi's branch refs/heads/main from Mark Payne
[ https://gitbox.apache.org/repos/asf?p=nifi.git;h=e1c8c96111 ]
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

This closes #6752.

> 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:
