Why low-latency Java still requires discipline

Sources: Chronicle Software, HN discussion
Summary: A Chronicle Software post argues that recent JVM garbage-collector advances do not remove the need for allocation discipline in latency-sensitive Java, and covers off-heap data, object reuse, and avoiding allocation on the hot path to keep tail latencies bounded. It reached the Hacker News front page on 2026-07-07.
Why it matters: Teams running latency-critical JVM systems still budget for allocation behavior rather than relying on collector improvements alone.
