JDK 27 Compact Object Headers: как сбросить до 30% кучи без кроссфита и жестких диет

Каждый Java-объект в HotSpot начинается со служебного заголовка размером 12 байт. В JDK 27 по умолчанию он сжимается до 8 — это JEP 534, финальный шаг внедрения Compact Object Headers. Для типовых бэкендов это 5–15% экономии heap, для приложений с миллионами мелких объектов (особенно на Scala, Clojure и иммутабельных коллекциях) — до 30%, без изменений в прикладном коде.
