This is probably something you should bring up on the net-dev mailing
list. The short answer is that shouldn't need any code changes to get
SDP to work with any java application on Linux as it's the interposer
library that does the protocol switching. The only issue you might have
is with IPv6 sockets (as the jdk uses IPv6 sockets by default when IPv6
is enabled) . Off-hand, I can't recall if libsdp handles IPv6 sockets.
If not, then running with -Djava.net.preferIPv4Stack=true forces the jdk
to use IPv4 sockets.
