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.
...
   
    Parameters:
       newAttr - The Attr node to add to the attribute list.
"

The implementation (JDK 1.4.0beta2, build b77) of the method
adds a new attribute node which can not be retrieved by getAttributeNode.

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;


import org.w3c.dom.NamedNodeMap;


public class test {

    public static void main(String argv[]) {

IIOMetadataNode elem = new IIOMetadataNode("elem");
MyTestAttrNode attrNode = new MyTestAttrNode("attr", "value");

elem.setAttributeNode(attrNode);


        Attr actValue = elem.getAttributeNode("attr");

        if(actValue == null) {
System.out.println("Failed - bad attrNode");
        }


        NamedNodeMap res = elem.getAttributes();

        System.out.println((res.item(0)).getNodeName());
        System.out.println((res.item(0)).getNodeValue());

    }
}

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


    public MyTestAttrNode(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;
    }
}
