#Hotpatching
I remember when kernel hotpatching came out, thinking "damn, there's a lot of people with expensive machines they can't turn off that'll never get this".

I have to hope they've another layer of security to deal with that.

✅ JDK 27 shipped yesterday with Shenandoah Late Barrier Expansion (JDK-8366041), gets us 0..20% throughput bump.
🔄 JDK 28 would hopefully ship in Mar 2027 with Shenandoah Hotpatching (JDK-8384415), gets us another 0..5% throughput bump.
🤘 JDK 29 in Sep 2027 would be awesome.

Hotpatching Went Free, Reboots Didn't Stop
Arc-enabled hotpatching for Windows Server 2025 became free in May 2026. But the 2026 calendar quietly undercuts the promise of four restarts a year.

【PC × OS更新】
Microsoft、Windows 11の再起動ポリシーを「月1回(Hotpatching導入)」へ移行

Microsoftは2026年9月1日、Windows 11のセキュリティ更新において、再起動なしでメモリ上に直接パッチを適用する「ホットパッチ(Hotpatching)」技術を一般PC向けに順次拡大し、システムの再起動頻度を原則「月に1回」へ削減する新ポリシーを発表しました。

これまでの頻繁な自動再起動による作業中断やゲーム・アプリのクラッシュストレスを劇的に軽減し、PCの連続稼働性とセキュリティパッチ適用率の両立を図る重要な改善となります。
