---------------------------------
Summary: Processors with RequiresInstanceClassLoading Classloading
are failing to get Instance ClassLoader during verify
Key: NIFI-15874
URL: https://issues.apache.org/jira/browse/NIFI-15874
Project: Apache NiFi
Issue Type: Bug
Reporter: Bob Paulin
When processors that have @RequiresInstanceClassLoading should be provided with
an instance classloader when verifyConfiguration is called[1]. The code has a
subtle bug where the getComponentType() is passed that only includes the
unqualified class name (ex MyClass) rather than the fully qualified class name
ex (org.apache.MyClass). This causes the StandardExtensionDiscoveringManager
to not find it's TempComponent which expects a fully qualified class name so it
determines an InstanceClassLoader is not required [2]. This is not an issue
with ControllerServices where the FQ Classname is passed.
