WeakishReference

public class WeakishReference extends Object
These classes are part of some code to reduce memory leaks by only retaining weak references to things on Java1.2+, and yet still work (with leaky hard references) on Java1.1. Now that Ant is 1.2+ only, life is simpler and none of the classes are needed any more. They are only retained in case a third-party task uses them
since
ant1.6
see
org.apache.tools.ant.util.optional.WeakishReference12
