 * RuntimeParameterAnnotationsTest is a test which checks that RuntimeVisibleParameterAnnotationsAttribute
 * and RuntimeInvisibleParameterAnnotationsAttribute are generated properly for constructors,
 * for static and abstract methods of class, for abstract, default and static methods of interface.
 * The test checks both single and repeatable annotations.
 * 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.
