(More precisely, when the corresponding instance of <CODE>File</CODE> is garbage collected.) This is done by the so-called reaper thread, which is started automatically when the class <CODE>FileCleaner</CODE> is loaded. It might make sense to terminate that thread, for example, if your web application ends.
