---------------------------------------
Summary: NiFi fails to start if there are nar's
innifi.nar.library.autoload.directory directory not readable by the user
starting up the JVM
Key: NIFI-7574
URL: https://issues.apache.org/jira/browse/NIFI-7574
Project: Apache NiFi
Issue Type: Bug
Components: Extensions
Environment: I can replicate using Apache NiFi 1.9.0
Reporter: Juan C. Sequeiros
NiFi fails to start if there are nar's in "extensions" directory not readable
by the user starting up the JVM.
On 1.9.0 probably other versions too.
If I put nar's on directory configured on the nar auto load dir:
nifi.nar.library.autoload.directory
That are not readable by the user starting up the NiFi JVM, NiFi fails to start
if restarted with NPE
