Alright, IIUC from private communication, I shouldn't have accepted the initial
patch.
# I didn't realize it was even possible to extract attachments {{-z}} and full
recursive parsing {{-J}} in the same command! Congratulations!!!
# Let's not do that.
Unless there are objections, I'll revert the {{-z}} behavior to print progress
to STDOUT.
Longer term, e.g. Tika 2.0, we could really do to fix up the commandline
processing and maybe use an actual commandline parser library, e.g. commons-cli.
FTR: I accept serious fault for introducing some true nuttiness in the
commandline, but here we are...

> Key: TIKA-3035
> URL: https://issues.apache.org/jira/browse/TIKA-3035
> Project: Tika
> Issue Type: Bug
> Components: app
> Affects Versions: 1.23
> Reporter: Soren Daugaard
> Priority: Major
> Labels: app, extract
> Attachments: testPDF_childAttachments.pdf
>
>
> 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}}:
> {code:java}
> $ java -jar tika-app-1.23.jar --extract-dir=tika-test/out/ -z
> testPDF_childAttachments.pdf 2> /dev/null
> {code}
> If I do not redirect stderr I see:
> {code:java}
> $ 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.

> In future versions of Tika, users may need to turn the TesseractOCRParser on
