IncompleteAnnotationException

AI-generated Key Takeaways

• IncompleteAnnotationException signals an attempt to access a missing element of an annotation, occurring when the element was added after compilation or serialization.

• This exception arises if the new annotation element lacks a default value and is accessed through reflection using the AnnotatedElement API.

• It provides methods to retrieve the annotation type (annotationType()) and the name of the missing element (elementName()).

public class IncompleteAnnotationException extends RuntimeException

Thrown to indicate that a program has attempted to access an element of an annotation type that was added to the annotation type definition after the annotation was compiled (or serialized). This exception will not be thrown if the new element has a default value. This exception can be thrown by the {@linkplain java.lang.reflect.AnnotatedElement API used to read annotations reflectively}.
