+ // avoid scanning non-reference fields. How reference fields are
+ // scanned is a bit tricky: we allocate using _Jv_AllocRawObj, which
+ // means that this memory will be scanned conservatively (same
+ // difference, since we know all the contents here are pointers).
+ // Then we put pointers into this memory into the 'fields'
+ // structure. Most of these are interior pointers, which is ok (but
+ // even so the pointer to the first reference field will be used and
+ // that is not an interior pointer). The 'fields' array is also
+ // allocated with _Jv_AllocRawObj (see defineclass.cc), so it will
+ // be scanned. A pointer to this array is held by Class and thus
+ // seen by the collector.
