One of the criterias for
instanceofto be true, is that the two classes must be loaded by the same classloader. This goes for class casting too.This would mean that instances of e.g.
Stringcreated by your class loader would not be compatible with theStringcreated by the system class loader. Are not instances of and cannot be cast to.You probably do not want that.
