method IIOMetadataNode.setAttributeNode does not work as described

Name: ipR10067 Date: 09/26/2001



Specification of the method
javax.imageio.metadata.IIOMetadataNode.setAttributeNode says:

"public Attr setAttributeNode(Attr newAttr) throws DOMException

   Adds a new attribute node. If an attribute with that name (nodeName)
   is already present in the element, it is replaced by the new one.
   ..."

However, the implementation (JDK 1.4.0beta3, build b80) of
the method does not work as described. The present attribute with the same name
is not replaced by the new one.

This bug affects new JCK tests:
api/javax_imageio/metadata/IIOMetadataNode/index.html#setAttributeNode[setAttributeNode003]
api/javax_imageio/metadata/IIOMetadataNode/index.html#setAttributeNode[setAttributeNode007]

To reproduce the bug run the following test:

------------ test.java ------------------------

import javax.imageio.metadata.IIOMetadataNode;
import org.w3c.dom.Attr;
import org.w3c.dom.Element;

public class test {

    public static void main(String argv[]) {

        String name = "name";
        String value = "right value";
        Attr actAttr;
        String actValue;
    
        IIOMetadataNode parent = new IIOMetadataNode("parent");
        MyAttrNode attrNode1 = new MyAttrNode(name);
        MyAttrNode attrNode2 = new MyAttrNode(name);

        attrNode1.setValue("wrong value");
        attrNode2.setValue(value);

        parent.setAttributeNode(attrNode1);
        parent.setAttributeNode(attrNode2); // should replace attrNode1
        
        actAttr = parent.getAttributeNode(name);
        actValue = actAttr.getValue();
        if (! actValue.equals(value)) {
           System.out.println("Failed! value is " + actValue);
           return;
        }
        System.out.println("Passed");
    }

}

class MyAttrNode extends IIOMetadataNode implements Attr {
    public Element owner;
    private String name;
    private String value;

    public MyAttrNode(String name) {
        this.name = name;
    }

    public MyAttrNode(String name, String value) {
        this.name = name;
        this.value = value;
    }
    public String getName() {
        return name;
    }
    public Element getOwnerElement() {
        return owner;
    }
    public boolean getSpecified() {
        return false;
    }
    public String getValue() {
        return value;
    }
    public void setValue(String value) {
        this.value = value;
    }
}
