/**

 * When a public class has a default access superclass with public members,
 * these members are accessible. Calling them from compiled code works fine.
 * Unfortunately, on some JVMs, using reflection to invoke these members
 * seems to (wrongly) prevent access even when the modifier is public.
 * Calling setAccessible(true) solves the problem but will only work from
 * sufficiently privileged code. Better workarounds would be gratefully
 * accepted.
