I would guess XDump is a class:
you can only invoke the "non-static" printPacket(...) on an object
instantiated from the class.
public class A {
public static void foo() {System.out.println("foo");}
public void bar() {System.out.println("bar");}
}
// elsewhwere
A.foo() // okay, foo is static, has no corresponding instantiated object
A.bar() // bad! bar is not static! (you can't invoke it directly on a class)
(new A()).bar() // okay, you are calling bar() on an instantiated object
