Garbage First (G1) Garbage Collector (GC) The G1GC is a server-style generational, incremental, parallel, mostly concurrent, stop-the-world evacuating garbage collector which is suitable for multiprocessor machines with a large amount of memory. G1GC aims to meets garbage collection pause-time goals with high probability, while achieving high throughput. G1GC monitors its stop the world pauses in … Read more

GC threads run in conjunction with application threads doing most of the GC work before pausing. Truly concurrent collectors are very hard to achieve as mutator threads keep modifying the state of the heap. Thus concurrent collectors are generally mostly concurrent implementation.
