Description

upon downloading the latest tika and trying basic commands it spews unwanted warnings, which makes parsing output necessary.

INFO  As a convenience, TikaCLI has turned on extraction of

This is not the default option in Tika generally or in tika-server.

The expected behavior is to return only the requested information. I do not see a switch to turn off or control unrequested warnings.

I can't imagine this is the correct behavior. It is not documented, nor could I find why such output exists.
