Otto Fowler commented on NIFI-8400: ----------------------------------- If you read this description, and initially thought "That variable name doesn't seem very long", please leave a comment here. :D > SystemDiagnostics throws NPE on Windows > --------------------------------------- > > Key: NIFI-8400 > URL: https://issues.apache.org/jira/browse/NIFI-8400 > Project: Apache NiFi > Issue Type: Bug > Components: Core Framework > Reporter: Matt Burgess > Priority: Major > > SystemDiagnostics includes some Long member variables such as openFileHandles > that are not populated on Windows, so they remain null and when > getOpenFileHandles() is called, the null is cast to a long which throws an > NPE. > The member variables should be long not Long, thereby getting a default value > of zero and avoiding an NPE when the values are not populated. If Long is > used elsewhere, a null check should be added to avoid possible NPEs when > calling the setter methods. -- This message was sent by Atlassian Jira (v8.3.4#803005)
