  * Test driver for MethodParameters testing.

  * The intended use of this driver is to run it, giving the name of
  * a single class compiled with -parameters as argument. The driver
  * will test the specified class, and any nested classes it finds.
  * <p>
  * Each class is tested in two way. By refelction, and by directly
  * checking MethodParameters attributes in the classfile. The checking
  * is done using two visitor classes {@link ClassFileVisitor} and
  * {@link ReflectionVisitor}.
  * <p>
  * The {@code ReflectionVisitor} test logically belongs with library tests.
  * we wish to reuse the same test-cases, so both test are committed together,
  * under langtools. The tests, may be duplicated in the jdk repository.
