It's not elegant but you could just use methods instead of labels...

public class KPatrick {
  public static void main(String[] args) {
    label1();
    for (int i = 0; i < 100; i++) boo();
    label2();
    for (int i = 0; i < 100; i++) mumble();
    label3();
    for (int i = 0; i < 100; i++) hiss();
  }

  static void boo() {}
  static void mumble() {}
  static void hiss() {}

  static void label1() {}
  static void label2() {}
  static void label3() {}

  static aspect A {
    before():
      execution(* *.label1()) {System.out.println("before label1");}
  }
}
