Thanks!

About the generics - some people have pointed out the same on reddit, and yeah, you are correct. The only thing that should be done is to read the Signature attribute that encodes the generic information about classes, methods, and fields (https://docs.oracle.com/javase/specs/jvms/se7/html/jvms-4.ht...)

As a matter of fact, I just did a test and the following code works! :-)

    public class Generic {
        public static void main(String[] args) {
            List<String> strings = new ArrayList<String>(10);
            strings.add("hey");
            strings.add("hackernews");

            for (String s : strings) {
                tempPrint(s);
            }
        }

        private static native void tempPrint(String value);
    }
