AnnotationTypeMismatchException

AI-generated Key Takeaways

• AnnotationTypeMismatchException signals an attempt to access an annotation element whose type has changed since compilation or serialization.

• This exception is thrown by the reflection API when reading annotations, specifically via AnnotatedElement.

• It provides methods to identify the incorrectly typed element (element()) and the unexpected data type found (foundType()).

• The exception includes details about the mismatched annotation element and the encountered data type.

public class AnnotationTypeMismatchException extends RuntimeException

Thrown to indicate that a program has attempted to access an element of an annotation whose type has changed after the annotation was compiled (or serialized). This exception can be thrown by the {@linkplain java.lang.reflect.AnnotatedElement API used to read annotations reflectively}.
