Have it been discussed whether that is feasible to modify the VM in

gets initialized?
The HotSpot VM does lazy resolution and it doesn't load the type of an
object if it's not initialized.
Static dependency refers to the types referenced in a class file (i.e.
any types directly referenced in the source).
So my question is: would it be possible to modify the component
responsible for this sort of dependency (I presume it must be some class
loader, right?) so that it would not load the classes until an instance
of a class gets initialized, or static methods get accessed, or the type
information gets requested (like Logger.class...)? In other words, if a
class has an *unused* field of type 'reference to an object of type T',
the class T would not be loaded at all until it really gets used in some
way.
Has that kind of solution been discussed?
