> 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.
