Subject Re: [jira] Assigned: (HARMONY-376) [classlib][luni] Generics uplift for java.lang.String and java.util.Comparator
Date Thu, 20 Apr 2006 06:15:54 GMT
Hi Nathan

This test:

public class test {
    public static void main(String[] args) throws Exception {
        String s1 = "string 1";
        Object o = s1;
        System.out.println(s1.compareTo(o));
        s1.compareTo(new Object());
    }
}

once compiled with javac 1.4 runs the same way on all: RI 1.5, RI 1.4,
and Harmony. Though it can't be compiled on javac 1.5

So compatibility is OK in this case, thanks for the patch

Thanks,
Mikhail
