You haven't cited anything except my own post, and your quotation of

On your part, Lew.

Wrong. Loading and initialization go hand-in-hand.

And not before.
When invoking a static method of a non-loaded class, the standard
procedure always has been:
Load the class.
Initialize the class.
Invoke the method.
In particular, the spec requires that in this:
class A {
static int x;
static { x = 100; }
static int foo () { return x; }
}
a call to A.foo() should return 100, not 0. If it can attempt to invoke
foo before the static initializer has executed that would be violated.
On the other hand, it complaining that a reflective call to A.bar()
can't be resolved sooner than the loading and initializing of A as part
of trying to resolve bar is equally anomalous. If it hasn't loaded and
initialized A yet, how can it be sure whether or not it has a method
bar? On the other hand, if it's a non-reflective call the code calling
bar won't even compile.
