JDK 16 was released on March 16, 2021. Java 16 removes Ahead-of-Time compilation (and Graal JIT) options. [340] The Java implementation itself was and is still written in C++, while as of Java 16, more recent C++14 (but still not e.g. C++17 or C++20) is allowed. The code was also moved to GitHub, dropping Mercurial as the source control system.

The rate of change over time in the JDK releases has remained largely constant for years, but under the six-month cadence the pace at which production-ready features and improvements are delivered has vastly improved. Instead of making tens of thousands of fixes and delivering close to one hundred JEPs (JDK Enhancement Proposals) every few years as...
JEP 409: Sealed Classes Sealed Classes allow API designers to specify which classes or interfaces may extend or implement a given class. Having an exhaustive list of cases to consider when modeling a problem can simplify development. JEP 409 was developed in the OpenJDK Project Amber, which aims to continually improve developer productivity through...
JEP 306: Restore Always-Strict Floating-Point Semantics The Java programming language and Java virtual machine originally only had strict floating-point semantics. Starting in JDK 1.2, small variances in those strict semantics were allowed by default to accommodate limitations of then-current hardware architectures. Those variances are no longer he...
JEP 391: macOS AArch 64 Port Delivers a version of the JDK for macOS that runs natively on Apple’s newer Arm 64 based systems.
JEP 406: Pattern Matching for switch Preview Enhances the Java programming language allowing pattern matching to be tested within a switch statement or switch expression. Using pattern matching in switch complex data-oriented queries can be expressed concisely and safely. JEP 406 was developed in the OpenJDK Project Amber. JEP 412: Foreign Function...
JEP 403: Strongly Encapsulate JDK Internals It will no longer be possible to relax the strong encapsulation of internal elements through a single command-line option, as was possible in JDK 9 through JDK 16 This change hides by default all but a few critical internal APIssuch as `sun.misc.Unsafe. It will still be possible to access existing interna...
JEP 411: Deprecate the Security Manager for Removal The Security Manager dates from Java 1.0. 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. JEP 398: Deprecate the Applet API for Removal The Applet API has become essentially irrelevant since all web-browser...
JEP 410: Remove the Experimental AOT and JIT Compiler The experimental Java-based ahead-of-time (AOT) and just-in-time (JIT) compiler saw little use since its introduction in JDK 9, more widely supported alternatives have emerged, and the effort required to maintain them is significant. As optional components, they were already removed from JDK 16....
