[Bug java/14979] New: gcj doesn't handle package private methods with differing return types properly

[ovidr at users dot sourceforge dot net]

one/A.java:

---------

package one;
public class A {

     public static void main(String[] s) {
          System.out.println("I'm a bug");
     }

     boolean test() {
          return false;
     }

}


two/B.java

-----
package two;

import one.A;

public class B extends A {

    void test () {

    }

}

works:
javac one\A.java
javac two\B.java

doesn't work with gcj:
gcj -C one\A.java
gcj -C two\B.java
two\B.java:8: error: Method `one.A.test()' was defined with return type 
`boolean' in class `one.A'.
        void test () {
                ^
1 error

tested on:
gcc version 3.4.0 20040316 (prerelease)
gcc version 3.5.0 20040414 (experimental)

Are you sure this is a bug?

Quote from the JLS:
http://java.sun.com/docs/books/jls/second_edition/html/classes.doc.html

8.4.6.3 Requirements in Overriding and Hiding
If a method declaration overrides or hides the declaration of another method,
then a compile-time error occurs if they have different return types or if one
has a return type and the other is void. Moreover, a method declaration must not
have a throws clause that conflicts (§8.4.4) with that of any method that it
overrides or hides; otherwise, a compile-time error occurs.

That tells me that a compile time error SHOULD occure because the return types
are different.

Take it all back. Vektor has corrected me. I hit this problem in Eclipse, and
did not notice the package visibility. Sorry for the bother.
