The G1 garbage collector is currently proposed to become the default garbage collector in JDK 9. Recently three new ideas for G1 were described on the hotspot-gc-dev at openjdk.java.net mailing list: - parallel full GC - throughput write barriers - rebuilding remembered sets during concurrent mark

This talk will present these three new ideas so that people who are interested in getting into G1 development know where to start, see what the existing code looks like today and highlight how one can contribute (it is not only about code!).

The presentation can be made longer if people want to dive deeper into the details (but it can also fit in a 25 minute slot).
