Open Source Java Virtual Machine Software - Page 3

This project is a simulation of an electromechanical computer based upon the design presented in Charles Petzold's book "CODE: The Hidden Language of Computer Hardware and Software"

Jem is a real time Java operating system designed for embedded devices. It focuses on a flexible and robust operating system architecture.

Mobile Java VM for PocketPC, WindowCE, Linux and Zaurus based portable devices, PDAs and SmartPhones, as well as Desktop Windows and Linux systems.

ExStudio is a set of development tools for the "Ex" virtual machine. It includes the vm itself, a compiler, an assembler and a debugger.

The Flexible Task Graphs programming model and supporting system for Java provides tools for very low latency real time programming in Java.

GC Analysis for IBM WebSphere JVM on iSeries. This tool helps analyze verbose garbage collection logs produced by WebSphere JVM on the AS/400 iSeries environment. Note: verbosegc option can be enabled by including the -verbosegc parameter.

High Availability using Virtualization: Set up two servers (main and backup). The backup should come into action when the main goes down, & should continue the operation that the main was running, exactly from the point of failure, without loss of data.

HyperVM is a multi-tiered, multi-server, multi-virtualization software product allowing a VPS vendor to provision, manage and delegate Xen or OpenVZ based virtual private servers. HyperVM allows users to manage VPS' across multiple servers transparently: it provides a mechanism to manage their networking configuration (IP address, gateway) from the control panel itself, and has a full-fledged IP address pool to facilitate large scale management. HyperVM also comes integrated with Kloxo hosting control panel which means that, using HyperVM, the provider can deploy a full fledged web hosting system out-of-the-box, HyperVM is tightly integrated with Kloxo, and all Kloxo functions can be accessed from HyperVM without needing to log into Kloxo.

IDEAIS is a enteprise service bus integration plataform for software development tools and activities. It uses Web Services (SOAP/HTTP) to integrate best of the breed software development tools (Eclipse, Subversion, Bugzilla, dotProject, vTiger).

The idea is to design simple computers, comparable to vintage homecomputers, large numbers of which are simulated on a PC in parallel. The machines connect to each other, with the goal of seeing efficient structures grow spontaneously, like crystals.

The Java Extended Memory Model extends the Java memory model to allow the sharing of persistent distributed objects between virtual machines.

JHaskell provides a Haskell interpreter and compiler for the JVM. The goal is to make Haskell a viable language for development for the Java platform and also to allow existing Haskell programs to run on the JVM.

JPPM is a packager manager for JPHP like npm or composer. JPPM will help you to build and run jphp applications or write new packages. JPHP is a new implementation for PHP which uses the Java VM. It supports many features of the PHP language (7.1+). How does it work? JPHP is a compiler like javac, it compiles PHP sources to JVM bytecode and then can execute the result on the Java VM. We develop a new IDE for beginners like Game Maker or Scirra Construct. It's based on JPHP, JavaFX, Java 8, and Gradle, and allows to creation of desktop games and apps for Linux, Windows, and Mac (maybe Android and other platforms in the future). JPHP is not a replacement for the Zend PHP engine or Facebook HHVM. We don’t plan to implement the zend runtime libraries (e.g. Curl, PRCE, etc.) for JPHP. PHP 7.1+ (and many language features from PHP 7.2, 7.3, 7.4). JIT (~2.5x faster PHP 5.6, ~1.1x faster PHP 7.0, ~13% slower than PHP 7.4, bench). Using java libraries and classes in PHP code.

This is a dynamic slicing tool for Java programs. The tool modifies the Kaffe virtual machine to collect the execution trace, and compress the trace on-the-fly. Please proceed to the tool's website http://jslice.sourceforge.net/ for download.

A set of tools and libraries that aim at simplifying multi-JRE Java application development.

JVix is a Java wrapper to the VMware VIX API, allowing control of virtual machines through a Java interface. Now on github: https://github.com/randomnoun/jvix

Multi-platform execution environment for applications (and libraries) based on bytecode (compile once, run anywhere). Support for multi-language and multi-paradigm. It intends to be an open alternative to the Java and MS.NET platforms.

Jasclipse is an Eclipse plugin for developing applications written in Jasmin. It provides Jasmin editor with syntax highlighting, error marking and Ctrl+Space assistance. It also allows compiling your files with Jasmin 2.2

Java Virtual System (JVS) is built around a virtual file system (VFS) - a common platform of Java, by Java, for Java. JVS extends JVM and makes it from an interpreter running half-compiled code a first-class server.

How can we easily develop applications for multicore or multicomputer architectures? We frequently use middlewares for that problem, but they are often complex and less productive. This way, at DECOM-UFOP, we have a middleware, named JavaCa&La or just JCL, to build portable and scalable solutions over many high performance computer architectures. Our middleware APIs is simple, intuitive and designed for young and senior programmers who don’t have high performance programming skills. Using our middleware, different programmers can develop applications in a collaborative way, i.e., one programmer application can read and write global variables from another application, developed by another programmer, in another machine, without explicit references. Existing Java applications can be executed by JCL. Low refactorings to insert distributed JCL maps in your existing code. Portable JCL code for multicore and multicomputer architectures.

PLEASE NOTE - JAVAPATHFINDER HAS MOVED TO: http://babelfish.arc.nasa.gov/trac/jpf Java PathFinder is a system to verify executable Java bytecode programs.

A Virtual Machine Linux appliance (for Virtualbox). This Fedora Remix puts emphasis on Java based applications. Includes OpenOffice.org, OpenJDK, browser plug-ins (IcedTea), and popular Java based applications like Azureus/Vuze, jEdit, and more.

Jelatine is a Java virtual machine implementing the Connected Limited Device Configuration of the Java 2 Micro Edition body of standards. It also includes its own CLDC-oriented classpath.

Java virtual machine following RTSJ-1.0 (Realtime Java) specifications.

The goal of the Jupiter project is to investigate scalable Java Virtual Machine (JVM) architectures. Jupiter is released under GPL, A modified version of GNU Classpath is used under GPL with Exceptions http://www.gnu.org/software/classpath/license.html
