FULL PRODUCT VERSION :
java version "1.5.0-beta2"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.5.0-beta2-b51)
Java HotSpot(TM) Client VM (build 1.5.0-beta2-b51, mixed mode, sharing)

ADDITIONAL OS VERSION INFORMATION :
Microsoft Windows XP [Version 5.1.2600]

A DESCRIPTION OF THE PROBLEM :
In java.text.ChoiceFormat

The method

    public void applyPattern(String newPattern) {

does the following on line 184

                if (segments[0].equals("")) {
                    throw new IllegalArgumentException();

But segments[0] is a StringBuffer, and so this test will always be false, as StringBuffer doesn't override equals.

I'm assuming you want

                if (segments[0].length() == 0) {
                    throw new IllegalArgumentException();



REPRODUCIBILITY :
This bug can be reproduced always.
