Mark Payne created NIFI-869:
-------------------------------
Summary: The logger used by processors, controller services, etc.
produces odd message when logging exception
Key: NIFI-869
URL: https://issues.apache.org/jira/browse/NIFI-869
Project: Apache NiFi
Issue Type: Bug
Reporter: Mark Payne
Priority: Minor
Fix For: 0.4.0
An easy way to reproduce this is to add a DBCPConnectionPool controller service
and use an invalid driver class name and attempt to enable the service. You'll
see a log message that indicates "Failed to invoke @OnEnabled method due to {}"
as seen below. The "due to {}" part is weird and should either log a toString
of the Exception or should not include the {}
