I've checked the same class with openjdk7 on my 10-CURRENT netbook:

$ java -version
openjdk version "1.7.0_17"
OpenJDK Runtime Environment (build 1.7.0_17-b02)
OpenJDK Client VM (build 23.7-b01, mixed mode)

$ netstat -an | fgrep 39999
tcp46      0      0 *.39999                *.*                    LISTEN

the 'tcp46' let me think, that the LISTEN is for both, IPv4 and IPv6,
and I can reach the server with

$ telnet ::1 39999
Trying ::1...
Connected to localhost.

and with

$ telnet 127.0.0.1 39999
Trying 127.0.0.1...
Connected to localhost.

Seems to work fine now.

Btw: How do they do this internally having only one Socket for both
families?
