Byte Buddy is a code generation and manipulation library for creating and modifying Java classes during the runtime of a Java application and without the help of a compiler. Other than the code generation utilities that ship with the Java Class Library, Byte Buddy allows the creation of arbitrary classes and is not limited to implementing interfaces for the creation of runtime proxies. Furthermore, Byte Buddy offers a convenient API for changing classes either manually, using a Java agent or during a build. In order to use Byte Buddy, one does not require an understanding of Java byte code or the class file format. In contrast, Byte Buddy's API aims for code that is concise and easy to understand for everybody. Nevertheless, Byte Buddy remains fully customizable down to the possibility of defining custom byte code. Furthermore, the API was designed to be as non-intrusive as possible and as a result, Byte Buddy does not leave any trace in the classes that were created by it.

A Java Virtual Machine for OpenJDK that's optimized for small footprint, fast start-up, and high throughput. Builds on Eclipse OMR and combines with the Extensions for OpenJDK for OpenJ9 repo. We're not sure which route you might have taken on your way here, but we're really pleased to see you! If you came directly from our website, you've probably already learned a lot about Eclipse OpenJ9 and how it fits into the OpenJDK ecosystem. Eclipse OpenJ9 is an independent implementation of a Java Virtual Machine. "Independent implementation" means it was built using the Java Virtual Machine specification without using any code from any other Java Virtual Machine. The OpenJ9 JVM combines with the Java Class libraries from OpenJDK to create a complete JDK tuned for footprint, performance, and reliability that is well suited for cloud deployments. The original source contribution to OpenJ9 came from the IBM "J9" JVM which has been used in production by thousands of Java applications.

The PHP script engine for Java. --- Run PHP applications within any J2EE server or servlet engine and/or connect script engines like PHP with Java or .NET back ends efficiently.

Simplify virtually executes an app to understand its behavior and then tries to optimize the code so that it behaves identically but is easier for a human to understand. Each optimization type is simple and generic, so it doesn't matter what specific type of obfuscation is used. Provides a virtual machine sandbox for executing Dalvik methods. After executing a method, it returns a graph containing all possible register and class values for every execution path. It works even if some values are unknown, such as file and network I/O. For example, any if or switch conditional with an unknown value results in both branches being taken. Analyzes the execution graphs from smalivm and applies optimizations such as constant propagation, dead code removal, unreflection, and some peephole optimizations. These are fairly simple, but when applied together repeatedly, they'll decrypt strings, remove reflection, and greatly simplify code. It does not rename methods and classes.

JNode is a Java New Operating system Design Effort. JNode is a simple to use and install Java operating system for personal use on modern devices. Any java application runs on it, fast and safe. See our homepage for additional information.

Infinity saves time and money by providing users with a virtual infrastructure without the need to buy and manage dedicated hardware. The Infinity virtualization platform gives users centralized management of their virtual machines (VMs), but unlike traditional virtualization solutions, Hosts running VMs can be any computer. Computer workstations and servers which are running Windows, Mac, Linux, BSD, Unix or no OS at all can be used to host VMs alongside their current applications. VMs can be run locally on workstations or they can be run on other Hosts and accessed remotely with the click of a mouse. VMs can be cloned, shared and teleported between Hosts in seconds. Using infinity can be as simple as plugging in an Infinity server, running the Infinity server in a VM, or booting a USB drive with Infinity installed on it. Then boot other computers from the network to run what ever you need. Installation details at http://www.techsologic.com/installing-infinity.php

VMware Tools Client allow you to execute scripts and transfert files on vSphere Virtual Machines through VMware Tools. http://pierrelx.com/vmware-tools-client Main features: - Commands / Scripts execution - Scripts stored in exportable ".db" file - Download file from virtual machines - Upload file to virtual machines - Ping test - Communicates with Virtual Machines only with VMware tools - Read only on vCenter API to discover inventory (will not scan the entire vCenter, it is live discovery) - vCenter URL/Login and Virtual Machine credentials stored in separeted and exportable ".db" file - Linux / Windows support - Multi VM view - JavaFX user interface

Avrora is a suite of tools for analyzing and debugging programs for AVR microcontrollers. It has support for a sensor platforms such as Mica2 and MicaZ, allowing wireless network simulation and allows dynamic instrumentation and static analysis.

An implementation of the MIDP2 specification on top of Java SE, to make it possible to use the same development tools during most development phases of a MIDlet as for a normal Java SE application.

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.
