The following example fails to create the new instance of com.sun.rowset.CachedRowSetImpl class under non-US locale with JDK 1.4.2.

package test;

import java.util.Locale;

public class Test {

    public static void main(String[] args) {
        try {
            Locale locale = Locale.getDefault();
            String suffix = locale.getCountry();
                         
            System.out.println(locale + " " + suffix );
                        
            Class clazz = Class.forName("com.sun.rowset.CachedRowSetImpl");
            System.out.println(clazz.newInstance());
        } catch (Exception e) {
            e.printStackTrace();
        }
    }
    
}

This code does not work under non-US locale with JDK 1.4:

> LANG=ru_RU /set/java/jdk1.4.2/linux-i586/bin/java -cp classes:/set/java-sqe/promotions/rowset1_0_1/rowset.jar test.Test

It works under US locale:

> LANG=C /set/java/jdk1.4.2/linux-i586/bin/java -cp classes:/set/java-sqe/promotions/rowset1_0_1/rowset.jar test.Test
en_US US
com.sun.rowset.CachedRowSetImpl@1d1acd3

It works under JDK 1.5:

>LANG=ru_RU /set/java/jdk1.5.0/linux-i586/bin/java -cp classes:/set/java-sqe/promotions/rowset1_0_1/rowset.jar test.Test
