This month\u2019s Java Annotated Monthly brings you the latest Java news, a generous dose of AI-focused articles, Kotlin updates, and highlights from a variety of technologies and frameworks, plus plenty more worth adding to your reading list.<\/p>\n

Our featured writer, Aicha Laafia<\/a>, takes a closer look at upcoming JEPs and shares her key findings on what may be next for Java. Let\u2019s dive in!<\/p>\n

September is here, and so is JDK 27<\/a>. Nine JEPs if you count the previews, and nothing to rewrite unless you are using preview features. Honestly? That\u2019s my favorite kind of release. You upgrade the version, and your app gets faster.<\/p>\n

The features that change your numbers<\/h3>\n

Compact object headers are on by default (JEP 534<\/a>). Headers shrink from 96 bits to 64, cutting heap usage by 10% \u2013 20% and pushing throughput up by 5% \u2013 10%. G1 also becomes the default garbage collector everywhere (JEP 523<\/a>), even on the small machines that used to get Serial GC instead, so check your smallest containers before you upgrade. For the full tour, Sven Woltmann<\/a> wrote a solid Java 27 breakdown<\/a>, and if video is more your thing, Catherine Edelveis<\/a> covers the whole release here<\/a>.<\/p>\n

Two security wins that protect you by default<\/h3>\n

JFR recordings collect environment variables and system properties, which is exactly where your tokens and passwords live, so Java 27 hides them for you (JEP 536<\/a>). And TLS 1.3 now gets post-quantum key exchange (JEP 527<\/a>), because attackers already save encrypted traffic, waiting for quantum computers to break it later. Java 27 makes sure they can\u2019t!<\/p>\n

Still on Java 8 or 11?<\/h3>\n

Don\u2019t jump, hop. Start now, LTS by LTS, and read my article Jurassic JDK: Migrate or Extinct<\/a> first. I covered everything I wish someone had told me before my first migration.<\/p>\n

Enjoy this month\u2019s Java Annotated Monthly!<\/p>\n
