RFR: 8266791: Annotation property which is compiled as an array property but changed to a single element throws NullPointerException [v6]

[Rafael Winterhalter]

> During annotation parsing, the parser assumes that a declared property is of an array type if the parsed annotation property is defined as an array. In this case, the component type is `null`, and a `NullPointerException` is thrown. This change discovers the mismatch and throws an `AnnotationTypeMismatchException`.
