For some reason, the java generator produces a bunch of extra methods whenever you have a field of a collection type. For instance if you have a field called "my_list", then you will get a "get_my_list_size()" method in addition to the standard getter and setter.
Personally I find these extra methods redundant, since all they save you is a pair of parentheses. I'd prefer to just get rid of them. Does anyone out there like or use these methods?
