+ * This is a JPF specific version of a system class because we can't use the real,
+ * platform VM specific version (it's native all over the place, its field
+ * structure isn't documented, most of its methods are private, hence we can't
+ * even instantiate it properly).
+ *
+ * Note that this class never gets seen by the real VM - it's for JPF's eyes only.
+ *
+ * For now this only supports a few basic methods.
