> java.text.ChoiceFormat.applyPattern(String) has different behavior with RI,
> 1. RI's java.text.ChoiceFormat.applyPattern(String) set pattern to be empty when the parameter doesn't start with number, but Harmony throws IllegalArgumentException.  
> 2. RI can parse the parameter correctly in which '<' follows first number, but Harmony throws IllegalArgumentException. 
> The following test case reproduces the bug,
> public void testApplyPattern() throws Exception{
>         ChoiceFormat f = new ChoiceFormat("");
>         //for difference 2
>         f=new ChoiceFormat("");
>         f.applyPattern("-1<is negative| 0#is zero or fraction | 1#is one | 1<is more than 1");
>         //for difference 1
>         f = new ChoiceFormat("");
>         f.applyPattern("-1#is negative|0#is zero or fraction|1#is one|1<is more than 1");
>         String str = "org.apache.harmony.tests.java.text.ChoiceFormat";
>         f.applyPattern(str);
>         String ptrn = f.toPattern();
>         assertEquals("Return value should be empty string for invalid pattern",
>                 0, ptrn.length());
> }
>  RI 5.0 passes these tests, but Harmony throws IllegalArgumentException.
