potential NPE(NullPointerException) in checkRemoveLabelsFromNode of CommonNodeLabelsManager. It because when a Node is created, Node.labels can be null. In this case, nm.labels; may be null. So we need check originalLabels not null before use it(originalLabels.containsAll). -- This message was sent by Atlassian JIRA (v6.3.4#6332)
