That's what I was alluding to in the parenthetical. According to the paper, C4 trades off a significant amount of throughput for reduced latency. That's what you want for many applications, and C4 is a great advance for those apps, but throughput is very important for most workloads, so HotSpot's GC ends up yielding a good balance.
