    Description

      FULL PRODUCT VERSION :
      java version "1.5.0_03"
      Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0_03-b07)
      Java HotSpot(TM) Client VM (build 1.5.0_03-b07, mixed mode, sharing)


      ADDITIONAL OS VERSION INFORMATION :
      Linux leeloo 2.6.8-2-k7 #1 Thu May 19 18:03:29 JST 2005 i686 GNU/Linux


      A DESCRIPTION OF THE PROBLEM :
      Parsing a ChoiceFormat with one of the characters

      * <
      * #
      * \u2264

      fails with IllegalArgumentException although this is not necessary. The reason is this code in ChoiceFormat.java:183

                  } else if (ch == '<' || ch == '#' || ch == '\u2264') {

      it checks for on of the special characters in the format. But it does this even in the 'body'-part of the pattern, i.e. the text to display. A fix would be to extend the if-clause to which part the special character is in and only run it if it is in the first part, i.e. choice-condition.

                  } else if (part == 0 && ch == '<' || ch == '#' || ch == '\u2264') {


      STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
      Just run one of these commands:

      new java.text.ChoiceFormat("0#<");
      new java.text.ChoiceFormat("0#a<b");

      EXPECTED VERSUS ACTUAL BEHAVIOR :
      EXPECTED -
      ChoiceFormat accepts '<', '#', '\u2264' in the body.
      ACTUAL -
      IllegalArgumentException

      ERROR MESSAGES/STACK TRACES THAT OCCUR :
      Exception in thread "main" java.lang.IllegalArgumentException
      at java.text.ChoiceFormat.applyPattern(ChoiceFormat.java:197)
      at java.text.ChoiceFormat.<init>(ChoiceFormat.java:294)


      REPRODUCIBILITY :
      This bug can be reproduced always.
