A New Model for Java Object Initialization #JVMLS

Presented by *Dan Smith* - Senior Developer (Java Platform Group - Oracle) during the *JVM* *Language* *Summit* (August 2024 - Santa Clara, CA).

_*Improving Field Initialization*_
_This video shows how we can co-evolve the Java language, JVM, and common coding practices to improve how fields are initialized, providing stronger guarantees about their contents._

_Goals include_
_1) eliminating the need for default values;_
_2) ensuring final fields cannot be observed to mutate; and_
_3) avoiding early publication of uninitialized objects._

_In Amber, Flexible Constructor Bodies allow Java code to initialize fields earlier than it could before, and in Valhalla, value classes have repurposed the ACC_STRICT flag to mark fields that support stronger guarantees._
