      Description



      Name: dkR10031 Date: 04/10/2001


      Specification of the method
      javax.imageio.metadata.IIOMetadataFormatImpl.getAttributeEnumerations says:

      "Throws: ...
               IllegalArgumentException - if the given attribute is not defined as an
               enumeration."

      However, the implementation (JDK 1.4.0beta, build b59) of the method
      throws IllegalStateException instead of IllegalArgumentException when given
      name of an attribute not defined as an enumeration.

      This bug causes failure of new JCK test:
      api/javax_imageio/metadata/IIOMetadataFormatImpl/index.html#getAttributeEnumerations

      To reproduce the bug run the following test:

      ------------ test05.java ------------------------
      import javax.imageio.metadata.IIOMetadataFormatImpl;
      import javax.imageio.ImageTypeSpecifier;

      class test05 {

          public static void main(String argv[]) {
              String[] result;
              
              MyFormatImpl fmt = new MyFormatImpl("root", 1, 10);
              fmt.addAttribute("root", "attr", fmt.DATATYPE_INTEGER, true, 2, 5);

              try {
                  result = fmt.getAttributeEnumerations("root", "attr");
                  System.out.println("failed: no Exception");
              } catch(IllegalArgumentException e) {
                  System.out.println("passed");
              }
          }
      }


      class MyFormatImpl extends IIOMetadataFormatImpl {

          MyFormatImpl(String root, int minChildren, int maxChildren) {
              super(root, minChildren, maxChildren);
          }

          public void addAttribute(String elementName, String attrName, int dataType,
                                   boolean required, int listMinLength, int listMaxLength) {
              super.addAttribute(elementName, attrName, dataType, required, listMinLength,
      listMaxLength);
          }

          public boolean canNodeAppear(String elementName, ImageTypeSpecifier imageType) {
              return true;
          }
      }

      The same problem occurs also for 4 more methods of IIOMetadataFormatImpl
      class:
          getAttributeListMaxLengthTests
          getAttributeListMinLengthTests
          getAttributeMaxValueTests
          getAttributeMinValueTests
      All they throw IllegalStateException instead of IllegalArgumentException
      when given name of an attribute not suitable for the request.
