| duke@435 | 25 | // An instanceRefKlass is a specialized instanceKlass for Java |
| duke@435 | 26 | // classes that are subclasses of java/lang/ref/Reference. |
| duke@435 | 27 | // |
| duke@435 | 28 | // These classes are used to implement soft/weak/final/phantom |
| duke@435 | 29 | // references and finalization, and need special treatment by the |
| duke@435 | 30 | // garbage collector. |
| duke@435 | 31 | // |
| duke@435 | 32 | // During GC discovered reference objects are added (chained) to one |
| duke@435 | 33 | // of the four lists below, depending on the type of reference. |
| duke@435 | 34 | // The linked occurs through the next field in class java/lang/ref/Reference. |

| duke@435 | 38 | // are linked to the static pending_list in class java/lang/ref/Reference, |
