The Stable Values API is a feature available for preview in Java 25 that allows developers to define immutable objects initialized at most once, offering the flexibility of lazy initialization with the performance benefits of final fields.
In this episode, Ana hosted Per Minborg, member of the Java Core Library team at Oracle and co-author of JEP 502 on Stable Values. Per discusses the essence of Stable Values and how this approach addresses the limitations of eager initialization in Java, enabling more efficient application startup by deferring the creation of expensive resources until they are actually needed. He also explains the design process and particularities of the API, emphasizing that Stable Values can be particularly beneficial in multi-threaded environments, ensuring thread-safe, at-most-once initialization without the complexity of traditional synchronization mechanisms.
