JEP 412: Foreign Function & Memory API (Incubator) To move Java forward, we intend to deprecate the Security Manager for removal in concert with the legacy Applet API (JEP 398).

It has not been the primary means of securing client-side Java code for many years, and it has rarely been used to secure server-side code. The Security Manager dates from Java 1.0. JEP 411: Deprecate the Security Manager for Removalĭeprecate the Security Manager for removal in a future release.
Retain the experimental Java-level JVM compiler interface (JVMCI) so that developers can continue to use externally-built versions of the compiler for JIT compilation. This compiler has seen little use since its introduction and the effort required to maintain it is significant. Remove the experimental Java-based ahead-of-time (AOT) and just-in-time (JIT) compiler. JEP 410: Remove the Experimental AOT and JIT Compiler Sealed classes and interfaces restrict which other classes or interfaces may extend or implement them. Remove the Remote Method Invocation (RMI) Activation mechanism, while preserving the rest of RMI.Įnhance the Java programming language with sealed classes and interfaces. JEP 406: Pattern Matching for switch (Preview)Įnhance the Java programming language with pattern matching for switch expressions and statements, along with extensions to the language of patterns.Įxtending pattern matching to switch allows an expression to be tested against a number of patterns, each with a specific action, so that complex data-oriented queries can be expressed concisely and safely. It will no longer be possible to relax the strong encapsulation of internal elements via a single command-line option, as was possible in JDK 9 through JDK 16. Strongly encapsulate all internal elements of the JDK, except for critical internal APIs such as. JEP 403: Strongly Encapsulate JDK Internals It is essentially irrelevant since all web-browser vendors have either removed support for Java browser plug-ins or announced plans to do so. JEP 398: Deprecate the Applet API for Removalĭeprecate the Applet API for removal. Implement a Java 2D internal rendering pipeline for macOS using the Apple Metal API as alternative to the existing pipeline, which uses the deprecated Apple OpenGL API. Provide new interface types and implementations for pseudorandom number generators (PRNGs), including jumpable PRNGs and an additional class of splittable PRNG algorithms (LXM). JEP 356: Enhanced Pseudo-Random Number Generators
This will restore the original floating-point semantics to the language and VM, matching the semantics before the introduction of strict and default floating-point modes in Java SE 1.2. Make floating-point operations consistently strict, rather than have both strict floating-point semantics (strictfp) and subtly different default floating-point semantics.
