This should be renamed to reflect that it is creating a new instance of a
VariableRegistry (line 48) and then copying the values from the passed
VariableRegistry and additionalAttributes into that new instance.
From looking at the method name and parameters, one would expect the passed
variableRegistry to be populated with the passed additionalAttributes.

> NIFI-1974 addressed this for the 0.x baseline but the PR does not apply
> cleanly to the 1.x baseline. Creating a separate JIRA for 1.x so that we can
> close out NIFI-1974 since 0.7.0 is ready to be released.
