Tim Allison commented on TIKA-3518:
-----------------------------------

I'm not seeing problems with 4.1.1 locally. 

I think we added more debugging/logging in 1.27 and 2.0.0.  Can you upgrade and see if the issue persists and/or what the cause might be?  Does tesseract return an exception, etc...

> ProcessBuilder not creating tmp file for Tesseract 4.1 and Higher Versions With Tika 1.26 and JDK 1.8
> I am working on a project which integrates Tika and Tesseract OCR Tika Version is 1.26, JDK 1.8 Now for any Tesseract Version earlier than 4.0 works fine and extracts the image/pdf data correctly But upgrading the TesseractOCR to 4.1.1 or Higher results in no data extraction. I debugged the issue and found that the ProcessBuilder is not creating the temporary txt output file from which TesseractOCR extracts the result, resulting in the issue. Any idea if this is a version compatibility issue Or How to resolve this?
