Upgrading your application’s dependencies already resolves most, if not all, of these issues.

#Java 16 released upgrade#

From my experience, the upgrade from Java 11 to Java 17 is easier compared to the upgrade from Java 8 to Java 11.

While upgrading Java can be challenging, it’s often a matter of hours or days.

If your application uses one of those features, then you need to resolve it when upgrading to a new version of Java.

Various features have been removed from the JDK such as fonts, certificates, tools and API methods.That way, everyone is more eager to continue with the upgrade. Your teammates and management can see it as well. Upgrade step-by-step so you can monitor the progress.Simply get started, spend some time on the upgrade, and determine where the issues are.This article and other resources can help solve common Java upgrading challenges.However, upgrading is often easier than originally thought. Estimating the amount of time and effort to upgrade to Java 16 or 17 may be difficult.Eliminated the cast of the loaded array element to Node, to prevent the situation when volatile fields are loading from arrays, losing type information about the element, and resulting in unneeded casts.Disable with -Dgraal.VectorizeHashes=false. Added support for vectorizing hashCode-like loops using the hash = c * hash + array.Enable it with -Dgraal.VectorizeSIMD=true. SIMD vectorization is still experimental and not enabled by default. Enhanced SIMD vectorization, to support vector byte reversal (e.g., Integer.reverseBytes).

#Java 16 released code#

Added a new optimization that analyzes code guarded by a conditional of the form x = y and replace all uses of x with y (or vice versa) if the replacement results in potential for further optimization.

Loop inversion is on by default and can be disabled with -Dgraal.LoopInversion=false. Inverted loops have superior characteristics for instruction level parallelism and optimization capabilities compared to regular, head counted loops. We have seem performance improvements of up to 30% for micro benchmarks exercising the inverted loop shape. This adds compiler support to generate inverted loops from regular ones.

Added a novel loop inversion optimization in GraalVM Enterprise.

#Java 16 released full#

These loops are subject to full unrolling, partial unrolling, guard optimization and vectorization. This new capability can be disabled with -Dgraal.DetectInvertedLoopsAsCounted=false. Added support to detect inverted (tail counted) loops as counted loops. GraalVM Enterprise now detects such loops as counted, enabling them to be analyzed and optimized like all other counted loops.

#Java 16 released windows#

Windows platform compatibility: To run GraalVM Community Edition based on OpenJDK 8u292 on a Windows platform, the MSVCR100.dll redistributable package needs to be installed (for more details, see the issue #3187).

Linux AArch64 platform compatibility: The GraalVM distributions for Linux AArch64 architecture remain experimental in this release. Supported features include the GraalVM compiler, the gu tool, the Node.js JavaScript runtime, Native Image, some developer tools.

GraalVM Enterprise Edition for macOS based on Oracle JDK 8 continue to be available.

MacOS platform support: Builds of GraalVM Community Edition for macOS based on OpenJDK 8 are no longer being produced.

Java 16 (experimental) support: The GraalVM distributions based on Oracle Java 16 and OpenJDK 16 are available for download.
