Code review request

[Brad Wetmore]

Two line code fix, but an important couple of lines.  :)

The underlying cipher still had buffered data when using Direct 
ByteBuffers.  This changes makes sure that data is read out.

     7142509: Cipher.doFinal(ByteBuffer,ByteBuffer) fails to process
     when in.remaining() == 0
