method is ambiguous

[gurpreet singh]

1. public class Test2 extends Test {

2.public static void main(String args[]) {
3.Test2 obj = new Test2();
4.final byte b = 10;
6.obj.name(b);
7.}

public static void name(short c) {
System.out.println(" short type from subclass.."+c);
}
}

public class Test {

public static void name(short c) {
System.out.println(" short type from superclass.."+c);
}
public static void name(byte c) {
System.out.println(" byte type from superclass.."+c);
}


}

The code at line number "6" "obj.name(b)" is giving error

ERROR:
The method name(short) is ambiguous for the type Test2

Why does the compiler considers widening conversion of byte to short in method invocation if there is a method in Superclass which can accept the byte as parameter?

if i remove "public static void name(short c) " from Subclass Test2, then it compiles correctly.

This shouldn't cause a compile error. Are you using Eclipse? From a cursory Google search, it seems that there was a bug in one of their earlier JDT versions that caused extraneous "method is ambiguous" errors.

Thanks Kelvin

You are right. Its the bug in eclipse.
