Compilation with Java 1.6.0_65 fails

I'm trying to follow the 'Getting started with Infinispan' as published here:
http://infinispan.org/docs/6.0.x/getting_started/getting_started.html

There, it is specified: "A Java 6.0 JDK"

Compiling INFINISPAN-7.0.0-SNAPSHOT with Maven 3.1.1 and java version "1.6.0_65, the maven-enforcer-plugin complains:
