rev 11078 : 8025619: (fc) FileInputStream.getChannel on closed stream returns FileChannel that doesn't know that stream is closed
Summary: If the stream is closed ensure getChannel() returns a closed channel. Also, FileKey.create() should throw an IOException directly instead of wrapping it in an Error.
