java.util.jar.Attributes.Name(String name) accepts empty String as
a parameter and creates a new object in JDK-1.2fcs.
However the JavaDoc for Attributes.Name(String name)says that
constructor throws "IllegalArgumentException - if the attribute name was invalid".

The constructor should recognize empty name as invalid attribute name and throw
IllegalArgumentException per Attribute.Name definition in JavaDoc:
"The Attributes.Name class represents an attribute name stored in this Map. Attribute names are
case-insensitive and restricted to the ASCII characters in the set [0-9a-zA-Z_-]."
 
Empty attribute name makes no sense and should not be allowed.

An example to reproduce this:
===== Test20.java ========
import java.util.jar.Attributes;
import java.util.jar.Attributes.Name;

public class Test20 {

    public static void main (String argv[]) {
        
        try {
            new Attributes.Name("");
        } catch (IllegalArgumentException iae) {
            System.out.println("Passed");
            return;
        }
        System.out.println("Failed: IllegalArgumentException expected");
        return;
    }
}

========= Sample run (JDK-1.2fcs) ==========
#>java Test20
Failed: IllegalArgumentException expected
