> I'm trying to wrap Weka, a popular machine learning system, with PyLucene.
> One of the Weka classes, weka.core.Utils, has a public static variable,
> and a public static method, with the same name (see below).  When I
> compile it, JCC has no way to say that, and I get the following:
> In file included from build/_test/__wrap__.cpp:5983:
