/**
 * The test checks that RuntimeVisibleAnnotationsAttribute and RuntimeInvisibleAnnotationsAttribute
 * are generated properly for top-level class (class, enum, annotation, interface),
 * for constructors (in enum and in class), for methods (abstract methods, static and default methods in interface),
 * for fields. The test checks both single and repeatable annotations.
 * In addition, all possible combinations of retention policies are tested.
 *
 * The test generates source code, compiles it and checks the byte code.
 *
 * See README.txt for more information.
