AF_INET6 support

Hi networking experts,

I've got a question regarding AF_INET6.

In jdk native code you'll still find lots of code guarded by  "#ifdef AF_INET6". I'm wondering if there are still supported build environments where AF_INET6 is not defined. Or is it time now to assume AF_INET6 and remove this guarding? Here at SAP we don't support non AF_INET6 build environments for quite a long time already. But probably there are scenarios out in the Java world where only IPv4 builds are done??

Maybe you can shed some light on this and/or give your opinion?

Thanks
Christoph
