That statement is incorrect.

There is only one static function / variable per class instance.

A class is uniquely identified by its name AND class loader.

Hence in a multiple class-loader environment like a Servlet container
(each webapp has its own class loader) you can have multiple classes
with the same name but different class loaders.
