Up to here, I can understand.

But you probably do NOT want this value, as we explicitly document that
our _LAST C enums are not constant (we reserve the right to add more
events), but merely aids for compilation to ensure that all cases are
covered compared to the current state of the libvirt.h header.
Trust me, I want this constant. ;-)
Note, that all those constants are private.
This constant is used in patch #41 to define the length of an array:
+ // registered event listeners by DomainEventID
+ private Map<EventListener, Integer>[] eventListeners =
makeHashMapArray(DomainEventID.LAST);
