Pascal Essiembre commented on TIKA-2490:
----------------------------------------

I still believe the warnings should be there by default for missing libs, or at 
a minimum having clear error messages to that effect when documents that would 
need them are encountered.  Otherwise people may think there is a bug in Tika 
or won't know why they get an exception and/or their document was not parsed.

What I would suggest though, is making it easier to turn off for those aware of 
those missing dependencies.  Why couldn't we use regular logging for those 
warnings instead?  I think it would align best with expectations if we could 
just turn it off by setting a higher log level in log4j configuration (or 
whatever logging implementation). 

Make sense?
