See the test case at the end of this message. With the JDK it will print:
Initialized
true
Class B is uninitialized prior to the instanceof operator. Note that
libgcj gets this wrong without your patch.

That's just how Java classloaders work. It is described extensively
(if not exactly) in the JLS.
public class A {
static B b;
public static void main(String[] args) {
System.out.println(b instanceof B);
}
}
class B {
static {
System.out.println("Initialized");
}
}
