Setting sun.locale.formatasdefault to true in Java 7

the following code will help illustrate my problem:

import java.util.Locale;
import java.text.*;

public class LocaleTest {
   public static void main(String[] args) {
      System.out.println(Locale.getDefault());
      System.out.println("java-version-" +System.getProperty("java.version"));
      System.setProperty("sun.locale.formatasdefault","true");
      System.out.println("prop:" +System.getProperty("sun.locale.formatasdefault"));
      System.out.println("getLocale-" +Locale.getDefault());
   }
}

As we know, there is bug in Java 7, in Locale.getDefault().However as recommended by Oracle I have set the system property 'sun.locale.formatasdefault' to true. Even though I am now getting my m/c Locale, it is always showing as en_US even though my m/c Locale is set to fr_BE.

Here is the output of above code, which is compiled and run on Java 1.7.0_09:

en_US
java-version-1.7.0_09
prop:true
getLocale-en_US

Any thoughts on what might be causing thus? Many thanks in advance.

You need to set that system property before starting up your JVM. You can do this via command line arguments:

java -Dsun.locale.formatasdefault=true TargetClass

Or in environments where you don't control the launching of the JVM, you can set it via _JAVA_OPTIONS environment variable:

  • *Nix

    export _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true

  • Windows

    SET _JAVA_OPTIONS=-Dsun.locale.formatasdefault=true

In Windows, if you want the change to be applied not only for that CMD but systemwide, you create a Windows System Variable JAVA_TOOL_OPTIONS
