JEP 401: Value Objects (Preview) merged to OpenJDK master

JEP 401: Value Objects has been merged into OpenJDK master, introducing a preview feature that enables more memory-efficient object models by allowing stack-allocated, immutable value types with strict field initialization. This foundational language enhancement will significantly improve application performance and memory footprint for Java workloads while requiring IT organizations to plan for Java version upgrades and evaluate their codebase for modernization opportunities. CIOs should anticipate that this feature will mature in upcoming Java releases, making it strategically important for long-term application architecture and cloud cost optimization.
