      Description



      Name: mlR10151 Date: 05/08/2001



      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() {}
      }
