When this test case is built with "ant", it generates a "Choices.java" with the
following (incorrect) instance variable:

    private wamu.xmlbinding.listbug.WeightedChoice _weightedChoice;

In 0.9.6, it generated instead:

    private java.util.ArrayList _weightedChoiceList;

In the new version, it does not generate a list object.
