Explore JEP 526's LazyConstant feature coming in JDK 26, a new type that addresses the challenges of lazy field initialization in Java while maintaining constant-folding optimization. Learn how LazyConstant uses a Supplier to initialize values exactly once and leverages the @Stable annotation to enable compiler optimizations. Discover the behavior patterns of LazyConstant, examine practical applications for lazy collections, and understand how this feature exemplifies OpenJDK's approach to developing and evolving Java features. Gain insights into the technical challenges of combining lazy initialization with performance optimization, and see how this API represents a significant improvement over traditional error-prone lazy initialization patterns.
