Description

In version 1.23 of Tika I am noticing a problem using the extract functionality. When extracting items from a file the "Extracting ... to ... " output goes to stderr instead of stdout.  

This problem is observed using the runnable jar `tika-app-1.23.jar` . 

Example to re-create problem:

Here we explode testPDF_childAttachments.pdf and redirects standard error to /dev/null:

$ java -jar tika-app-1.23.jar --extract-dir=tika-test/out/ -z testPDF_childAttachments.pdf 2> /dev/null

If I do not redirect stderr I see:

$ java -jar tika-app-1.23.jar --extract-dir=tika-test/out/ -z testPDF_childAttachments.pdf
INFO  As a convenience, TikaCLI has turned on extraction of
inline images for the PDFParser (TIKA-2374).
Aside from the -z option, this is not the default behavior
in Tika generally or in tika-server.

WARNING: Tesseract OCR is installed and will be automatically applied to image files unless
you've excluded the TesseractOCRParser from the default parser.
Tesseract may dramatically slow down content extraction (TIKA-2359).
As of Tika 1.15 (and prior versions), Tesseract is automatically called.
In future versions of Tika, users may need to turn the TesseractOCRParser on via TikaConfig.

Using 1.22 I correctly see the extracted files in stdout when redirecting stderr:
