Exception in Tika 1.5 (when reading "values" from metadata)

[jipis]

If you parse the file at https://github.com/roo-rb/roo/blob/master/test/files/Pfand_from_windows_phone.xlsx with yomu and get the metadata, the resulting object is "False" -- which leads to all sorts of fun. Even reading the text from the file generates a Java exception (though the read method returns "").

I've found that Tika 1.5 seems to be the issue; Tika 1.7 (and there are even-newer versions) successfully reads this file. (I saw someone forked and upgraded to 1.8 but the pull request didn't go through due to CI tests not passing.)

I guess this can be closed since Tika was updated in #32?
