Jukka Zitting resolved TIKA-388.
--------------------------------

       Resolution: Fixed
    Fix Version/s: 0.7
         Assignee: Jukka Zitting

As of revision 925217 the AutoDetectParser wraps all incoming streams to BufferedInputStream
regardless of whether they claim mark support or not. Resolving as fixed.

> As seen on tika-dev@ and in JCR-2576, there are some InputStream implementations that
claim to support the mark feature, but lose the mark as soon as the end of stream has been
reached. There's no way for a client to detect such behaviour, so it's probably best for Tika
to always use BufferedInputStream to wrap incoming streams when mark support is needed. This
may cause one layer of extra buffering, but avoids problems with such broken streams.
