Ok so in seeing this part of the stackdump we know there is a
'classpath thing' going on
"Caused by: java.lang.ClassNotFoundException: org.mitre.nifi.NiFiNITFReader"
And we see from your provided info that your jar does contain such a class
"22243 Wed Oct 21 10:36:46 EDT 2015 org/mitre/nifi/NiFiNITFReader.class"
And we see that you have a service loader manifest
"808 Wed Oct 21 10:36:42 EDT 2015
META-INF/services/org.apache.nifi.processor.Processor"
QUESTIONS:
-------------------
Can you please provide content of that service manifest file?
Also can you please provide the log information that writes out on
startup which shows the processors/extensions that load?
It looks like this...
2015-10-21 09:20:32,520 INFO [main]

Thanks!
