The description for the javax.imageio.metadata.IIOMetadata class reads:

protected IIOMetadata(boolean standardMetadataFormatSupported,
                      String nativeMetadataFormatName,
                      String nativeMetadataFormatClassName,
                      String[] extraMetadataFormatNames,
                      String[] extraMetadataFormatClassNames):

No words here about the situation if extraMetadataFormatNames.length > extraMetadataFormatClassNames.length.


public IIOMetadataFormat getMetadataFormat(String formatName):

No words about ArrayIndexOutOfBoundsException


But getMetadataFormat throws ArrayIndexOutOfBoundsException in the example below:
========================== a.java =============================
import javax.imageio.metadata.IIOMetadata;
import org.w3c.dom.Node;

public class a extends IIOMetadata {
    static String[] sarr1 = {"name1"};
    static String[] sarr2 = {};

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

    public a() throws Exception {
        super(true, null, null, sarr1, sarr2);
        getMetadataFormat("name1");
    }

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

    public boolean isReadOnly() {
        return true;
    }

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

    public void reset() {}
}
