    29  * Thrown when an application tries to access a type using a string

    33  * checked exception, whereas this exception is unchecked.

    35  * <p>Note that this exception may be used when undefined type variables

    36  * are accessed as well as when types (e.g., classes, interfaces or

    37  * annotation types) are loaded.

    38  * In particular, this exception can be thrown by the {@linkplain

    39  * java.lang.reflect.AnnotatedElement API used to read annotations

    40  * reflectively}.
