I don't get a compilation error when I build R3 with Ant, but Eclipse always shows a compilation error in AbstractTypeMap. It's 50th line: public Set<Entry<? extends B>> entrySet() { | return entrySet; | } saying that 'the return tpe is incompatible with TypeMap.entrySet().' Any clue? I am using JDK 6 both in Eclipse and Ant (i.e. command line). View the original post : http://www.jboss.com/index.html?module=bb&op=viewtopic&p=4124710#...
