> After analyzing the stack trace and little experimentation, we found that
> "env" is unix/Mac OS X/Linux specific command and does not work on Windows.
> We were able to workaround this problem by adding some Windows specific code,
> recompile Tika and run again with similar setup. I am attaching the original
> file and modified file for review.
> If fix is acceptable by Tika specific standards, I can send the pull request
> on Github to contribute the patch.
