-/**
- * Test driver for MethodParameters testing.
- * <p>
- * 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.
