                 URL: https://jira.jboss.org/browse/JBIDE-7076
             Project: Tools (JBoss Tools)
          Issue Type: Bug

1) Open some persistent.xml with Flow Editor;
2) make some random changes: add "Start Event", "End Event", "Rule"
3) Ctrl-S - I saw the editor rewrite content of my test persistent.xml;
4) press Ctrl-Z - undo - get exception:

"Undo" did not complete normally.  Please see the log for more information.
