Two loopback adapters communication in windows 7 or 8

by

Once our development systems are upgraded from windows XP to windows 7, my debug setup has stopped working.
Steps followed in original setup (Windows XP):

  1. Add two loopback adapters
  2. Assign ipv4 172.16.16.1 to one adapter and 172.16.24.1 address to another adapter
  3. Start an Java application (source code is with us) which will bind to 172.16.24.1 address
  4. Start another Java application (source code is not with us), which will bind to 172.16.16.1

Both application will run on same machine and they will start communication to each other. Everything works!
I have followed the similar procedure in windows 7 and 8, but it did not worked.
I have captured the wireshark logs for both the loopback adapters and one packet for each are as follows:
