java.text.NumberFormat is incorrectly deserialized for some locales.

Name: avC70361 Date: 05/18/98



  Th java.lanag.NumberFormat instances obtained with method
getCurrencyInstance(Locale locale) for some locales are incorrectly deserialized
in jdk1.2beta4 when have been serialized in jdk1.1.6.

Here is the test demonstrating the bug.
-----------NumberFormatTest.java----------
import java.util.Locale;

public class NumberFormatTest {

  public static void main(String args[]) {

    Locale[] locales = {
      Locale.CANADA,
      Locale.CANADA_FRENCH,
      Locale.CHINA,
      Locale.CHINESE,
      Locale.ENGLISH,
      Locale.FRANCE,
      Locale.FRENCH,
      Locale.GERMAN,
      Locale.GERMANY,
      Locale.ITALIAN,
      Locale.ITALY,
      Locale.JAPAN,
      Locale.JAPANESE,
      Locale.KOREA,
      Locale.KOREAN,
      Locale.PRC,
      Locale.SIMPLIFIED_CHINESE,
      Locale.TAIWAN,
      Locale.TRADITIONAL_CHINESE,
      Locale.UK,
      Locale.US
    };

    if (args[0].equals("write")) {

      ObjectOutputStream stream = null;

      try {

        stream = new ObjectOutputStream(new FileOutputStream(args[1]));

        for(int i = 0; i < locales.length; i++) {
          stream.writeObject(NumberFormat.getCurrencyInstance(locales[i]));
        }

        stream.close();

      } catch(IOException e) {
        System.out.println("Couldn't write to " + args[1] + " : " + e);
        System.exit(1);
      }

      System.out.println(args[1] + " written successfully");

    } else if (args[0].equals("read")) {

      ObjectInputStream stream = null;

      try {

        stream = new ObjectInputStream(new FileInputStream(args[1]));

      } catch(Exception e) {
        System.out.println(
          "Failed: couldn't read from" + args[1] + " : " + e
        );
        System.exit(1);
      }

      int errors = 0;

      for(int i = 0; i < locales.length; i++) {
        try {
          NumberFormat format = (NumberFormat)stream.readObject();
          if (!format.equals(NumberFormat.getCurrencyInstance(locales[i]))) {
            System.out.println("Failed for locale : " + locales[i] + " : format returned is not equal to expected");
            errors++;
          }
        } catch(Exception e) {
          System.out.println("Failed for locale : " + locales[i] + " : " + e);
          errors++;
        }
      }

      if (errors == 0) {
        System.out.println("Passed");
      }

    }

    System.exit(0);

  }

}
