Spring Improper @AliasFor configuration now results in an exception

Given the following composed @ContentRespBody annotation:

@Target({ElementType.TYPE, ElementType.METHOD})
@Retention(RetentionPolicy.RUNTIME)
@Documented
@ResponseBody
public @interface ContentRespBody {
    @AliasFor(annotation = ResponseBody.class)
    Class<? extends ResultForm> value() default ContentResultForm.class;
}

Regarding the meta-annotation @ResponseBody, version 5.0.7 will not report an error, but when upgrading to version 5.2.4, it will report an error.

Is this a bug or an expected result?

That is the expected behavior, since ResponseBody in fact does not declare an attribute named value.

Thus, annotating the value attribute in your custom annotation with @AliasFor(annotation = ResponseBody.class) is a configuration error.

If you do not see an error for that in Spring Framework 5.0.7, that simply means that the error detection has improved in Spring Framework 5.2.
