Create a non static nested class without enclosing class throws VerifyError

A DESCRIPTION OF THE PROBLEM :
Creation of a static child class(AA) of an non static class(A) without enclosing class (EnclosingClass) throws VerifyError at runtime instead of an compiler error at compile time.

STEPS TO FOLLOW TO REPRODUCE THE PROBLEM :
Run the code provided

EXPECTED VERSUS ACTUAL BEHAVIOR :
EXPECTED -
compile time error
ACTUAL -
VerifyError at runtime:
Exception in thread "main" java.lang.VerifyError: Bad type on operand stack
Exception Details:
  Location:
    EnclosingClass$A$AA.<init>()V @2: getfield
  Reason:
    Type uninitializedThis (current frame, stack[1]) is not assignable to 'EnclosingClass$A$AA'
  Current Frame:
    bci: @2
    flags: { flagThisUninit }
    locals: { uninitializedThis }
    stack: { uninitializedThis, uninitializedThis }
  Bytecode:
    0000000: 2a2a b400 01b7 0007 b1

at EnclosingClass$A.create(EnclosingClass.java:12)
at EnclosingClass.main(EnclosingClass.java:18)

---------- BEGIN SOURCE ----------
public class EnclosingClass {

    public abstract class A {

        public static class AA extends A {

        }

        public static A create() {
            return new AA();
        }

    }

    public static void main(String[] args) {
        A.create();
    }

}

---------- END SOURCE ----------

CUSTOMER SUBMITTED WORKAROUND :
Make A static - it should not compile this way.

FREQUENCY : always
