The compiler must reject cyclic annotation element types.
Javac spits out an error for nest(): "cyclic annotation element type".

@Retention(RetentionPolicy.RUNTIME)
@interface Nested {
	String name() default "Hans";
	N2 nest();
}

@interface N2 {
	Nested n2() default @Nested(name="Haus", nest= @N2);
}

Running the following class then gives a StackOverflowError (cyclic annotations
seem to pass through the verifier without problems):

@Nested(name="XY", nest= @N2)
class Test {
	public static void main(String[] args) {
		Nested annotation= Test.class.getAnnotation(Nested.class);
	}
}
