> StrSubsitutor caches a references to SystemProperties statically on first class references.  This does not work properly with System.setProperties().  For example the following code:
> {code}
> package test.utilities;
> import java.util.Properties;
> import org.apache.commons.lang.text.StrSubstitutor;
> public class TestStrSubstitutor {
>     public static void main(String[] args) {
>         System.out.println(StrSubstitutor.replaceSystemProperties("os.name=${os.name}"));
>         Properties testProps = new Properties();
>         testProps.put("test_key",  "test_value");
>         testProps.putAll(System.getProperties());
>         System.setProperties(testProps);
>         System.out.println(StrSubstitutor.replace("test_key=${test_key}", System.getProperties()));
>         System.out.println(StrSubstitutor.replaceSystemProperties("test_key=${test_key}"));
>     }
> }
> {code}
> produces the following output:
> {code}
> os.name=Windows 7
> test_key=test_value
> test_key=${test_key}
> {code}
> The code linked here shows the static caching of the System Properties reference: http://commons.apache.org/proper/commons-lang/apidocs/src-html/org/apache/commons/lang3/text/StrLookup.html
