Github user olegz commented on the issue: https://github.com/apache/nifi/pull/397 The DLLs are distributed with the Tesseract JAR, but not _.so_ or other OS specific libs. Basically the current JAR only supports Windows out-of-the-box. @joewitt If I understand correctly we need to create a custom validator with something like this inside it ``` new Tesseract(); ``` . . . basically a throw-away instance of Tesseract just to see if it loads successfully as that is where JNA mapping happens
