> 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.
