Description Thomas.Aigner

Build Identifier: I20100608-0911

overloading a static generic method doesn't work any more.
It works in javac 1.6 and eclipse 3.5

Reproducible: Always

Steps to Reproduce:
compile:
import java.util.List;

public class CovarReturnTest {

    public static String doIt(final List<String> arg) {
        return "1";
    }

    public static CharSequence doIt(final List<CharSequence> arg) {
        return "2";
    }
}

I believe this was a bug in java 6 which got fixed in java 7. See that this test case doesnt compile with java 7 (b76), giving an error "name clash.... same erasure". Eclipse compiler also gives the same error and is thus compatible with javac and also JLS3 - 8.4.3.
Srikanth, whats your take?
