[wildfly-dev] wildfly 8 client library now requires Java 7 ?

[David M. Lloyd]

There are one or two API features that will give you an unsupported 
error on JDK 6; everything else is emulated (though XNIO does not use 
much NIO.2 stuff because mostly it's junk anyway).

In particular I removed the 1.6 NIO UDP multicast emulation in 3.1 
because nobody was using it anyway.  Now it only works in 1.7+.

Everything used by WildFly should work in 1.6.
