According to the spec., javax.imageio.metadata.IIOMetadata.getExtraMetadataFormatNames


      Returns:
            an array of Strings with length at least 1, or null.

But it returns array of zero length.
To reproduce the bug run the following example:


========================== a.java =============================
import javax.imageio.metadata.IIOMetadata;
import org.w3c.dom.Node;

public class a extends IIOMetadata {
    static String[] sarr = {};

    public static void main (String argv[]) throws Exception {
        new a();
    }

    public a() {
        super(true, null, null, sarr, sarr);

        String[] names = getExtraMetadataFormatNames();
        if( names != null && names.length < 1 )
            System.out.println("Failed");
        else
            System.out.println("Passed");
    }

    public Node getAsTree(String formatName) {
        return null;
    }

    public boolean isReadOnly() {
        return true;
    }

    public void mergeTree(String formatName, Node root) {}

    public void reset() {}
}
