getFooList method not get created when using JDK 1.6

I have an element 'foo' which can occur multiple times.  When I generate the class files using JDK 1.5, I get the method getFooList.  When I generate the class files using JDK 1.6, the method getFooList does not exist.  Is this expected behavoir?  Why does the getFooList method not get created when using JDK 1.6?  I am using XmlBeans 2.4.0

Thanks,

Nathan
