GraalVM is a Java VM and JDK based on HotSpot/OpenJDK, implemented in Java. It supports additional programming languages and execution modes, like ahead-of-time compilation of Java applications for fast startup and low retention footprint. The showtime product-ready version, GraalVM xix.0, was released in May 2022.[v] The near contempo version is GraalVM 21.3.0, made available in October 2022.

Major differentiators of GraalVM compared to the base of operations JDK are:

  • GraalVM Compiler, a JIT compiler for Java
  • GraalVM Native Paradigm, allowing the ahead-of-fourth dimension compilation of Java applications
  • Truffle Language Implementation framework and the GraalVM SDK, to implement additional programming language runtimes
  • LLVM Runtime and JavaScript Runtime

Project goals [edit]

  • To improve the functioning of Java virtual machine-based languages to match the performance of native languages.[6] [vii]
  • To reduce the startup fourth dimension of JVM-based applications by compiling them ahead-of-time with GraalVM Native Image technology.
  • To enable GraalVM integration into the Oracle Database, OpenJDK, Node.js, Android/iOS, and to support like custom embeddings.
  • To allow freeform mixing of code from whatsoever programming linguistic communication in a unmarried program, billed as "polyglot applications".[6] [eight]
  • To include an easily extended fix of "polyglot programming tools".[6] [nine]

History [edit]

GraalVM has its roots in the Maxine Virtual Motorcar project at Sun Microsystems Laboratories (now Oracle Labs). The goal was to write a Coffee virtual machine in Java itself, hoping to free the development from the issues of developing in C++, particularly manual memory management, and benefit from meta-circular optimizations. Upon realizing that writing everything in Coffee was besides ambitious every bit a first step, the conclusion was taken to focus on the compiler merely and hook information technology into Hotspot, to reuse as much equally possible the Hotspot runtime. The GraalVM compiler was started past manually converting the code of the Hotspot client compiler (named "C1") into Java, replacing the previous Maxine compiler.[x]

Graal was included in HotSpot-based Java VM releases similar OpenJDK from Java 9 through 15, but was removed in Coffee sixteen for lack of use.[11]

Releases [edit]

GraalVM is production-ready software, bachelor as Community Edition for an open up-source license and as Oracle GraalVM Enterprise Edition accessible by accepting the OTN License Agreement Oracle GraalVM Enterprise Edition Including License for Early on Adopter Versions.[12] Oracle Corporation appear the release of Oracle GraalVM Enterprise Edition on viii May 2022.[thirteen] GraalVM can substitute a default JDK on Linux and macOS platforms on x86 64-chip systems.

GraalVM 20 [edit]

GraalVM xx.three.0

GraalVM 20.iii.0 was released in November 2022.[14] It was marked every bit the first LTS enterprise version of GraalVM and every bit the final release for 2022. This version supports code sharing in the GraalVM LLVM runtime, allowing the AST and compiled code of common bitcode libraries to be shared between multiple contexts inside a single engine.

GraalVM 20.1.0

GraalVM xx.1.0 was released in May 2022.[xv] It included several improvement for many of the components. Too performance improvements, usability fixes for native-image were published. The JavaScript engine supports all ECMAScript 2022 mode features by default. The regular expression engine (TRegex) used by JavaScript and Python supports all expressions now. Ruby (TruffleRuby) improved in compatibility with native gems.

GraalVM twenty.0.0

GraalVM 20.0.0 was released in February 2022.[16] It improved in its Windows back up, brought an enhanced native-prototype tool and improved the tooling support, amid many detailed changes in the compiler and supported languages.

GraalVM 19 [edit]

GraalVM 19.0.0

The back up on Windows is currently nether development and released as an early adopter functionality in GraalVM 19.0.

GraalVM 19.0 is based on meridian of JDK version 8u212.

Components [edit]

The GraalVM compiler is shipped with the components of a normal Java virtual automobile (OpenJDK). Additional components are included in GraalVM to support new execution modes (GraalVM Native Image) or programming languages (LLVM runtime, GraalVM JavaScript equally a potential replacement to the deprecated Nashorn engine, TRegex as a regular expression engine).

GraalVM Compiler [edit]

The GraalVM Compiler is a modern Java only-in-time compiler. It complements or replaces the existing compilers (C1/C2 in HotSpot). In dissimilarity to those existing compilers, the GraalVM compiler is written in modular, maintainable and extendable way in Coffee itself.

It is released nether GPL version 2 with the classpath exception.

GraalVM Native Image [edit]

GraalVM Native Image is an ahead-of-fourth dimension compilation technology that produces executable binaries of class files.[17] It is released as an early adopter plugin, which means it is production-set only may include backport incompatible updates in the future releases.

This functionality supports JVM-based languages, just tin optionally execute dynamic languages, developed on top of GraalVM with Truffle framework. The executable file does not run on a JVM and uses necessary runtime components as thread scheduling or GC from "Substrate VM" - a trivial version of a virtual automobile. Since the resulting native binary includes application classes, JDK dependencies and libraries already, the startup and execution time reduces significantly.

GraalVM Native Epitome is officially supported by the Fn, Gluon, Helidon, Micronaut, Picocli, Quarkus, Vert.x and Jump Boot Java frameworks.[18] [xix] In September 2022, Oracle detailed plans to add ahead-of-time compilation to the OpenJDK using the GraalVM compiler for Java 9.[twenty] [21] This proposal, tracked past the JEP 295: Ahead-of-Time Compilation, was included in Coffee 9.[22] The experimental utilize of GraalVM every bit a just-in-fourth dimension compiler was added for the Linux x86-64 platform for Java ten.[23]

The jaotc command creates a Native Prototype.[24] The experimental -Xx:+EnableJVMCIProduct flag enables the use of Graal JIT.[25]

Truffle Language Implementation Framework [edit]

In clan with GraalVM, Oracle Labs developed a language abstract syntax tree interpreter called "Truffle" which would let it to implement languages on top of the GraalVM.[26] [27] Many languages have been implemented in Truffle, including a C interpreter challenge to be nigh as fast as GCC and Clang.[28]

The Truffle framework and its dependent part, GraalVM SDK, are released under the Universal Permissive License, version 1.0, to encourage utilize of the framework for projects which do not want to be bound by the copyright or other parent rights.

Instrumentation-based Tool Support [edit]

A major advantage of the GraalVM ecosystem is language-agnostic, fully dynamic instrumentation back up congenital-in directly into the VM runtime. Execution events can exist captured by API clients with overhead that is extremely low in fully optimized code.[29] [30]

The core GraalVM installation provides a language-agnostic debugger, profiler, heap viewer, and others based on instrumentation and other VM support.[9] GraalVM likewise includes a backend implementation of the Chrome Inspector remote debugging protocol.[31] Although designed originally for JavaScript debugging, it can exist used to debug all GraalVM languages from a browser.

Language and Runtime Support [edit]

GraalVM is written in and for the Coffee ecosystem. Information technology can execute applications written in all languages that compile to the Java bytecode format, eastward.thou. Java, Scala, Kotlin, and more.

Based on Truffle Language Implementation framework additional languages can be supported in GraalVM.

  • GraalVM JavaScript:[32] ECMAScript 2022 compliant JavaScript runtime, with support for Node.js
  • TruffleRuby:[33] Ruby-red language implementation with preliminary support for Cherry on Rails
  • FastR:[34] R linguistic communication implementation
  • GraalVM Python:[35] Python iii language implementation
  • GraalVM LLVM Runtime (SuLong):[36] LLVM bitcode interpreter implementation
  • GraalWasm:[37] [38] A WebAssembly implementation

Support for boosted languages tin can be implemented by users of GraalVM. Some notable third-political party linguistic communication implementations are grCuda,[39] SOMns,[40] TruffleSqueak,[41] [42] and Yona.[43]
