I am learnging Java memory management, From what I already learned from internet.
Minor GC is triggered when Eden space is full, Minor GC will copy objects still being referenced to one survivor space which is empty, but that space is smaller than Eden, What will collector do when eden is full of alive objects ? AFAIK,Java GC Collector is copying collector, it should move all live objects away then clear old memory space.

Minor GC is triggered when Eden space is full
almost correct. A minor GC can be triggered when a major GC is triggered. It's like the GC says : "I need to do a Full GC, but first I'll do a minor one". In that case (G1
does this, for example), Eden space
might not be full.
When that happens (some Eden
regions could not be completely evacuated), those regions are made old, as even commented here:
Regions that failed evacuation are always made old...
