 * The test checks that RuntimeVisibleAnnotationsAttribute and RuntimeInvisibleAnnotationsAttribute
 * are generated properly for inner classes, for constructors, for methods, 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.
