I have just joined this group and since last year I started to study HotSpot more in detail. I have a question for you, so your input will be greatly appreciated.
Based on my understanding Dirty Cards Write Barrier is a way of keeping track of references from Old to Young Generation. This technique is used during minor GC to search for objects referred from Old generation.
Is this technique used by all minor GC: Serial, Parallel, Parallel Old, CMS, G1? Are there any other Write Barrier techniques?
