      Description



      Name: nkR10003 Date: 07/03/2002



      The JavaDoc comments for RandomAccessFile.close() method says:
      /**
       * ...
       *
       * If this file has an associated channel then the channel is closed as well.
       *
       * ...
       *
       */

      This statement does not work.

      Example below demonstrates this problem:
      ------------------example--------------------
      import java.io.*;
      import java.nio.channels.*;

      public class test {
          public static void main(String[] args) {
              File f = new File("test.txt");
              try {
                  f.createNewFile();
                  f.deleteOnExit();
                  RandomAccessFile raf = new RandomAccessFile(f, "r");
                  FileChannel channel = raf.getChannel();
                  raf.close();
                  if (channel.isOpen()) {
                      System.out.println("Test failed: channel is open");
                      System.exit(-1);
                  }
              } catch (IOException e) {
                  System.out.println("Test failed: unexpected exception: " + e);
              }
              
              System.out.println("Test passed");
              return;
          }
      }
