Hi Vyom, I had a quick glance through your changes.
Apart from the suggestions you've already got (use snprintf instead of string concatenation, method ordering...), I think "src/jdk.net/macosx/classes/jdk/net/UnixSocketOptions.java" and " src/jdk.net/macosx/native/libextnet/UnixSocketOptions.c " should be renamed to MacOSXSocketOptions.<java/c> to be consistent with the other platforms (Linux and Solaris at the moment). Furthermore, I think most of the options can/should also be supported for AIX. I'm willing to contribute this. However, I should probably do this in a separate bug once you have completed your work on this one. I would also add TCP QUICKACK then.
