Hi Mark,

I tried to see whether I can reproduce this behavior in my Ubuntu (GNOME 
Desktop) machine.
I created a mime type "application/rajendra gutupalli" which contains a 
space in sub type and
able to get this mime type using Path.probeContentType(). This mime type 
should have been filtered by the implementation.

Steps to be followed to create mime type in Ubuntu.

 > created mime type file raj.xml file in the /usr/share/mime/packages/ 
directory
<mime-info xmlns='http://www.freedesktop.org/standards/shared-mime-info'>
        <mime-type type="application/rajendra gutupalli">
                <comment>Word document</comment>
        <glob pattern="*.raj"/>
        <alias type="application/vnd.rajendra"/>
        </mime-type>
</mime-info>

rajendra at client24: sudo update-mime-database /usr/share/mime

 >Files.probeContentType() returns the following string.
application/rajendra gutupalli

we will get to know exact behavior for this scenario once Alan is back 
to work.

Thanks
Rajendra.
