I have looked further into this issue, and the issue is actually a bug in FileInputStream. Basically, every class that derives from InputStream needs to implement the reset() method, and FileInputStream neglects to do so.
Please see this in the InputStream source code: <https://lh5.googleusercontent.com/-YogltbfLGX4/UYFag1esuRI/AAAAAAAAAbw/SLb_MigbW9Y/s1600/reset.png> Thanks.
