JEP 500: Java to Enforce Strict Final Field Immutability by Restricting Reflection

JEP 500 prepares the Java ecosystem for final field integrity in JDK 26, restricting deep reflection mutations. This crucial update aims to enhance safety and performance by closing a long-standing loophole, transitioning toward stricter encapsulation. Developers can now anticipate warnings when attempting these mutations, ensuring a reliable path for future optimizations. By A N M Bazlur Rahman
