NIFI-15874: FQ class name to ExtensionManager to get InstanceClassloader
(#11176)
> 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
> Priority: Minor
> Time Spent: 20m
> Remaining Estimate: 0h
>
> 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.
