@valeriepeng I totally agree about `@throws`. I was just going for consistency 
within the file. There are other `@exception` appearances.

Yes, I do agree about the `update(ByteBuffer)` in Mac as well; however this one 
throws `IllegalArgumentException` if the parameter is null. Or were you 
referring to another version of the `update` method?
