an on-going effort to develop a lightweight, secure virtual machine for executing Java bytecode. The VM is intended to be an extension framework for applications or devices that dynamically load and execute untrusted extensions
Avian is a lightweight virtual machine and class library, both written from scratch to provide a useful subset of Java's features.
C# Java Virtual Machine
C# Java Virtual Machine is a tiny implementation of the Java VM, including simple native classes. It written using the C# language. The VM is very easily expandable by writing additional native or Java classes.
A research Java Virtual Machine developed at the Vienna University of Technology and released under the GPL. The VM uses a compile-only approach, which means there is no interpreter available. The optimizing JIT compiler is available for a number of architectures.
(commercal) a Java VM implemented as a combination of three major components: (1) optimizing ahead-of-time (AOT) compiler, which transforms your Java applications into native binary executables; (2) caching JIT compiler, responsible for handling dynamically loaded classes that could not be precompiled; (3) high performance runtime, implementing support for Java memory management, threading, synchronization, exceptions
conforms to the JVM specification version 2 (blue book). In comparison to most other VM's (free and commercial) it is extremely small, with a stripped executable on PowerPC of only ~90K, and Intel 70K. However, unlike other small VMs (e.g. KVM) it is designed to support the full specification, and includes support for object finalisation and the Java Native Interface (JNI)
Jato is a Java virtual machine implementation with a Just-in-time (JIT) compiler. It can currently run some simple Java programs on i386 running under Linux.
Java IBM Developer Kit
Java Developer Kit for Linux is IBM's latest Java port for Linux
Java PathFinder (JPF) is a system to verify executable Java bytecode programs. In its basic form, it is a Java Virtual Machine (JVM) that is used as an explicit state software model checker, systematically exploring all potential execution paths of a program to find violations of properties like deadlocks or unhandled exceptions.
JavaDesktopEngine is a Java engine capable of running several programs within the same VM instance, without launching lots of VMs for simple processes. Services exposed can be accessed by trivial XML-RPC calls.
Jikes RVM is a research virtual machine developed at the IBM T. J. Watson Research Center.
joeq virtual machine
a Java 2 (JDK 1.3) compatible virtual machine. joeq is unique in that it is entirely implemented in JavaTM, leading to greater reliability, portability, maintainability, and efficiency. It is also language-independent, so code from any supported language can be seamlessly compiled, linked, and executed --- all dynamically
Jupiter Java Virtual Machine is designed for modularity and extensibility.
a JIT compiler
kissme is a Java Virtual Machine (JVM) freely available under the GPL. It is still in an early development stage but can run simple Java programs.
NanoVM is a tiny (less than 8 kB of code including simple native classes and a bootloader) implementation of the Java VM. It currently runs on Linux and the AVR microcontroller family.
Open Runtime Platform: an open source research infrastructure project that provides these features thus enabling the rapid evolution of systems research of dynamic compilation and memory management
The goal of this project is to build an efficient Java virtual machine in C for the GNU/Linux operating system. SableVM implements the Java virtual machine specification, second edition.
teaseme is a JVM that runs in the linux kernel.
a high performance Java Virtual Machine (JVM) for use on servers, fully implementing the latest Java standards from Sun
