注释中的泛型类型

考虑以下代码:

import java.lang.annotation.Retention;
import java.lang.annotation.RetentionPolicy;

public class AnnotationTest {

    @GenericAnnotation<String>(foo = "Test")
    public class Bar1 {

    }

    @ObjectAnnotation(foo = "Test")
    public class Bar2 {

    }

    @WorkingAnnotation(foo = "Test")
    public class Bar3 {

    }

    @Retention(RetentionPolicy.RUNTIME)
    public @interface GenericAnnotation<T> {

        public T foo();

    }

    @Retention(RetentionPolicy.RUNTIME)
    public @interface ObjectAnnotation {

        public Object foo();

    }

    @Retention(RetentionPolicy.RUNTIME)
    public @interface WorkingAnnotation {

        public String foo();

    }

}

Bar1 根本不会编译.一大堆错误.
