Japanese character problem while using “JISAutoDetect” encoding with Java1.4.2

    Details

      Description

      Some Japanese characters have a problem while using the “JISAutoDetect” encoding with Java1.4.2_26. The issue does not fail in JDK 5.0_22 or 6.0_19.
       

      Steps to run the test case

      1. Set LANG to 'ja_JP.PCK'

      2. Javac and run.
      java moji2 | od -x

       Here is the test result.

      JDK 1.4.2_26

        /opt/java14224/bin/java moji2 | od -x

        0000000 815b 3f8a 8740 3f54 3f41 3f55 0a00

                     ==

       So the first byte of 0x878a is converted to 0x3f.

      JDK 6u19

        /opt/java16006/bin/java moji2 | od -x

        0000000 815b 878a 8740 8754 8741 8755 0a00

                     ====

       The value 0x878a, is the correct result.

      Testcase is attached, and appended below:
      import java.io.*;
      import java.net.*;

      public class moji2 {

          public static void main(String[] args) {

              try{
              String str = "¿[¿¿¿@¿T¿A¿U";

              byte[] bytes = str.getBytes("MS932");
              String str2 = new String(bytes, "JISAutoDetect");
      // String str2 = new String(bytes, "MS932");
              System.out.println(str2);
              }catch(UnsupportedEncodingException e){
                  e.printStackTrace();
              }

        }
      }
