/**
* Exception used to signal that a write intended to overwrite a value previously
* read encountered an underlying version conflict during an atomic compare-and-swap
* operation. This generally means that another node has written to the value since
* we last read it, and that the information we hold may be stale.
*
* Upon receiving such an exception, the caller should no longer assume it holds
* up-to-date information and should drop any roles that build on top of such an
* assumption (such as leadership sessions).
