Was trying to understand why old generation mx bean was notified in case of
G1GC and saw following code
// young collection set counters. The _eden_counters,
// _from_counters, and _to_counters are associated with
// this "generational" counter.
// old collection set counters. The _old_space_counters
// below are associated with this "generational" counter.
I don't see these counters updated anywhere. What is the use of these
counters in G1GC.
only following is updated in g1CollectedHeap.cpp
// incremental collections both young and mixed
// full stop-the-world collections
Is there any mail thread/doc which explains more about this.
