java.text.MessageFormat.parse fails with ChoiceFormat

Name: dfC67450 Date: 03/11/98



Object[] java.text.MessageFormat.parse(String text, ParsePosition pp)
fails when first formatter is ChoiceFormat and first prefix has length
greater than 2.

Here is the test demonstrating the bug:

-----------------TestMF.java------------------------
import java.text.*;

public class TestMF {
    public static void main (String args[]){
        MessageFormat mf = new MessageFormat("");
        String pattern = "{0,choice,1#YES|2#NO}";
        String prefix = "";
        for (int i = 0; i < 5; i++) {
          String formatted = prefix + "YES";
          mf.applyPattern(prefix + pattern);
          prefix += "x";
          Object[] objs = mf.parse(formatted, new ParsePosition(0));
          System.out.println(i + ". pattern :\"" + mf.toPattern() + "\"");
          System.out.print(" \"" + formatted + "\" parsed as ");
          if (objs == null) System.out.println(" null");
          else System.out.println(" " + objs[0]);
        }
    }
}
---------Output from the test ---------------------
0. pattern :"{0,choice,1.0#YES|2.0#NO}"
 "YES" parsed as 1.0
1. pattern :"x{0,choice,1.0#YES|2.0#NO}"
 "xYES" parsed as 1.0
2. pattern :"xx{0,choice,1.0#YES|2.0#NO}"
 "xxYES" parsed as 1.0
3. pattern :"xxx{0,choice,1.0#YES|2.0#NO}"
 "xxxYES" parsed as null
4. pattern :"xxxx{0,choice,1.0#YES|2.0#NO}"
 "xxxxYES" parsed as null
