IIOMetadataNode.setAttributeNode: unexpected IIODOMException

Name: dkR10031 Date: 05/15/2001


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

"public Attr setAttributeNode(Attr newAttr) throws DOMException"

However, the implementation (JDK 1.4.0beta, build b64) of the method
throws IIODOMException: Node not an IIOAttr! when a legal Attr parameter
is passed to the method. Note that the spec does not describe IIOAttr
class.

This bug affects new JCK test:
api/javax_imageio/metadata/IIOMetadataNode/index.html#setAttributeNode

To reproduce the bug run the following test:

------------ test08.java ------------------------
import javax.imageio.metadata.IIOMetadataNode;
import org.w3c.dom.Attr;
import org.w3c.dom.Element;

public class test08 {

    public static void main(String argv[]) {

IIOMetadataNode elem = new IIOMetadataNode("elem");
MyAttrNode attrNode = new MyAttrNode("attr", "2001");

elem.setAttributeNode(attrNode);
attrNode.owner = elem;

System.out.println("Passed");
    }
}

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;
    }
}
