inner class inheritance with outer class inheritance can't find constructor

Instantiation fails at runtime if I have an inner class extending an inner class defined in the outer class's parent I get a NoSuchMethodError on instantiation. In other words, C2 extends C1 and C2.B extends C1.A yields C1$A: method <init>()V not found in C2.B's constructor. A repeatable test case is below:

class FailingInnerClassInheritance {
	
	public static void main(String[] args) {
		new C2()
	}
	
}

class C1 {
	class A {}
}

class C2 extends C1 {
	{ new B() }
	class B extends C1.A {}
}

The analogous example works in Java. It fails in Groovy even if we construct B later (after C2 construction) and try to supply various explicit constructors.
