> Many users have complained about the difficulty of diagnosing unexpected
> behavior when a {{nifi.properties}} value does not match the desired value
> perfectly. Many property accessors perform an exact string match, and
> leading/trailing spaces can cause this to fail silently. This is especially
> to diagnose because it is often not apparent in the text editors used to
> display the properties file or log messages.
> The property value should have both leading and trailing space trimmed before
> being consumed.
