Build Identifier: 3.7.0 final Eclipse release, xtext distro from itemis

The xtend2 compiler generates invalid java code for the following function:

def toSeparatedString(Iterable<T> i, (T)=>String toStringFunc, String separator){
	i.map(T x | toStringFunc.apply(x)).join(separator)
}


The result looks as follows:

public String toSeparatedString(final Iterable<?> i, final Function1<?,String> toStringFun, final String separator) {
    final Function1<?,String> _function = new Function1<?,String>() {
        public String apply(final ? x) {
          String _apply = toStringFun.apply(x);
          return _apply;
        }
      };
    Iterable<String> _map = IterableExtensions.<?, String>map(i, _function);
    String _join = IterableExtensions.join(_map, separator);
    return _join;
  }


The inner apply Method uses ? as a type

Reproducible: Always
