Programming with Minimal Values
summary
Minimal Value Types are a VM-first experiment that lets the JVM derive flattened runtime types from an ordinary annotated POJO via a value capable class annotation, producing a generated runtime class (e.g. Point$Value) and new bytecode actions like default value, vwithfield and boxing/unboxing. MethodHandle adaptations handle calls and boxing, and the prototype ships an interpreter plus C2 JIT on Linux x64 with an experimental javac extension; early benchmarks report noticeably improved layout and performance.
