-----------------------------------
Summary: onPropertyModified() called before @OnEnabled for
controller services on nifi startup
Key: NIFI-7275
URL: https://issues.apache.org/jira/browse/NIFI-7275
Project: Apache NiFi
Issue Type: Bug
Affects Versions: 1.10.0
Reporter: Nissim Shiman
On nifi startup, the onPropertyModified() [1] is run for each property of a
controller service.
This is run before the ControllerService methods annotated with @OnEnabled [2]
are run.
So, when onPropertyModified() references properties that are initialized in the
method with @OnEnabled, a java.lang.NullPointerException occurs
