Make the pointuct 'public'...

  public abstract pointcut test();

Notice the same behavior with abstract classes and methods, though jikes 
seems to be a bit more informative:

package p1;
public abstract class A { abstract void f(); }

-------

package p2;
public class C extends p1.A { void f() {} }

     2. public class C extends p1.A { void f() {} }
                     ^
*** Semantic Error: The abstract method "void f();",
    belonging to the superclass "p1.A", has default access,
    so it is not inherited and cannot be implemented in this
    package. Therefore, class "p2.C" must be abstract.
