FULL PRODUCT VERSION :
1.6.0_18

ADDITIONAL OS VERSION INFORMATION :
Windows 7 Enterprise 64-bit

A DESCRIPTION OF THE PROBLEM :
Javac (any version) compiles the attached code without error, but when Main is run it prints "X.Q" instead of "A<T>.X.Q" as required by the language specification.  I think this is really a shortcoming of the specification for circular class declarations, but demonstrating my point is easier if I just start by reporting it as a compiler bug.


STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Compile and run attached program

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
A<T>.X.Q

-or-

Compilation error complaining about base class circularity.

REPRODUCIBILITY :
This bug can be reproduced always.

---------- BEGIN SOURCE ----------
class A<T> {
  static class X {
    static class Q {
      public static void main() {
        System.out.println("A<T>.X.Q");
      }
    }
  }
}

class B extends A<B.Y.Q> {
  static class Y extends X { } // X here is inherited from A
}

class X {
  static class Q {
    public static void main() {
      System.out.println("X.Q");
    }
  }
}

class Main {
  public static void main(String[] args) {
    B.Y.Q.main();
  }
