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

"public Attr setAttributeNode(Attr newAttr) throws DOMException
 ...
 Specified by:
       setAttributeNode in interface Element
 ..."

and specification of the method org.w3c.dom.Element.setAttributeNode says:

"public Attr setAttributeNode(Attr newAttr) throws DOMException
 ...

 Throws:
   ...
       INUSE_ATTRIBUTE_ERR: Raised if newAttr is already an attribute of
       another Element object.
   ..."


However, the implementation (JDK 1.4.0beta3, build b80) of the method does not
throw DOMException if newAttr is already an attribute of another Element object.


This bug affects new JCK tests:
api/javax_imageio/metadata/IIOMetadataNode/index.html#setAttributeNode[setAttributeNode001]
api/javax_imageio/metadata/IIOMetadataNode/index.html#setAttributeNode[setAttributeNode005]

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[]) {

        IIOMetadataNode parent = new IIOMetadataNode("parent");
        IIOMetadataNode elem = new IIOMetadataNode("elem");

        MyAttrNode attrNode = new MyAttrNode("name", "value");
        elem.setAttributeNode(attrNode);
        attrNode.owner = elem;
    
        try {
            parent.setAttributeNode(attrNode);
        } catch(org.w3c.dom.DOMException e) {
            if (e.code != org.w3c.dom.DOMException.INUSE_ATTRIBUTE_ERR) {
                System.out.println("Failed! Invalid exception code: " + e.code);
                return;
            }
            System.out.println("Passed");
            return;
        }
        System.out.println("Failed to throw DOMException");
    }

}

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