/**
 * The test checks that RuntimeVisibleAnnotationsAttribute and RuntimeInvisibleAnnotationsAttribute
 * are generated properly for inner classes enums, for constructors, for methods,
 * for fields (enum, class, annotation, interface). 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.
