While working on JDK-7131356 an issue on whether UI elements such as JFileChooser, which uses native CocoaUI underneath, should be displaying localized message or not.

The fix to JDK-7131356 involved dropping the call to "JRSSetDefaultLocalization" in "setupMacOSXLocale", file jdk/java_props_macosx.c because it did not seem to do what it was supposed to (as told by Apple), ie. showing localized messages in native UI.

This issue is filed to answer definitively what the correct behavior should be.
