      Name: mlR10151 Date: 04/10/2001



      According to the spec.
      public void seek(long pos) throws IOException
       . . .
      Throws:
           IndexOutOfBoundsException - if pos is smaller the the flushed position.
                                                          ^^^ typo copied from the spec.

      But it does not throw any exception:
      ===================== a.java =======================
      import java.io.*;
      import javax.imageio.stream.*;

      public class a {
          public static void main (String argv[]) throws Exception {
              File f = new File("a.java");
              FileImageInputStream fiis = new FileImageInputStream(f);
              fiis.flushBefore(2);
              try {
                  fiis.seek(0);
                  System.out.println("Failed");
              } catch (IndexOutOfBoundsException e) {
                  System.out.println("Passed");
              }
          }
      }
