Hi Balchandra:
I checked it out with Java 7 on FreeBSD:
==== SNIP ====
[uschindler@lucene ~]$ cat Test.java
import java.util.Locale;
public class Test {
public static void main(final String[] args) throws Exception {
Locale.setDefault(new Locale("tr", ""));
Process exec = Runtime.getRuntime().exec("ls");
}
}

On MacOSX:

-> So it seems that Apple's JDK6 is immune. Unfortunately I don’t have a
FreeBSD version available. I also have no Solaris or AIX one.
