Different targets of the secure values proposal embrace decoupling the creation of secure values from their initialization, with out vital efficiency penalties; guaranteeing that secure values are initialized not more than as soon as, even in multi-threaded applications; and enabling person code to soundly get pleasure from constant-folding optimizations beforehand solely out there to JDK-internal code. It’s not a aim of the proposal to reinforce Java with a method to declare secure values or to change the semantics of ultimate fields.
In explaining the motivation for the secure values proposal, the JEP notes that Immutability has benefits, as a result of an immutable object will be solely in a single state and subsequently will be shared freely throughout a number of threads. The Java platform’s software for managing immutability is ultimate fields, however ultimate fields have limitations, such because the must be set eagerly, that prohibit their applicability in lots of real-world functions.
