Hi Brent,

I am not an expert here, and I am hoping someone from I18N
also reviews this.

A nit
- " LC_ALL" + LC_ALL + "\n" +
+ " LC_ALL=" + LC_ALL + "\n" +

If Mac is the only system affected by this, should we make the checks for
LC* and LANG specific to Macs since other platforms don't have this issue ?
I am concerned this might pass vacuously on systems configured correctly.

Since the test extends TestHelper all you have to do is:

-        if("C".equals(LANG) || "C".equals(LC_ALL)) {
+        if (isMacOSX && ("C".equals(LANG) || "C".equals(LC_ALL))) {
