Subject Re: NIFI connecting to Activemq
Date Sun, 10 Jan 2016 01:25:19 GMT
Chris,

Thanks for sending the screenshot.  The NullPointerException is
trivially reproduced using your settings.  I didn't even need a JMS
server to cause it.

Have created a JIRA for this: https://issues.apache.org/jira/browse/NIFI-1378

Thanks!
Joe
