* Abstract class that maps Class objects to lazily-computed values of

* to determine how the values are computed.
*
* The keys are only weakly reachable through this map, so this map
* does not prevent a class (along with its class loader, etc.) from
* being garbage collected if it is not otherwise strongly reachable.
* The values are only softly reachable through this map, so that the
* computed values generally persist while not otherwise strongly
* reachable, but their storage may be reclaimed if necessary. Also,
* note that if a key is strongly reachable from a value, then the key
* is effectively softly reachable through this map, which may delay
* garbage collection of classes (see 4429536).
