AAAA records are not part of the issue... if you want a quick and dirty 
test, try this

1. download http://javassh.org/download/jta26.jar this is a java/swing 
telnet client

2. Run
   java -jar jta26.jar <someipaddress>
and you get:
   Socket: can't connect: java.net.SocketException: Invalid argument

3. Run
   java -Djava.net.preferIPv4Stack=true -jar jta26.jar <someipaddress>
and it works (assuming there is a telnet server there to connect to)

At least that is how things behave for me.
