In the process of checking usage of com.sun.java.accessibility.util.java.awt.*Translator.java I found this code in com.sun.java.accessibility.util.Translator.getTranslatorClass:

            t = Class.forName("com.sun.java.accessibility.util."
                              + c.getName()
                              + "Translator");

So apparently at some point someone did some refactoring and that is now dead code because there are no *Translator classes in com.sun.java.accessibility.util.
