Kaffe is a clean room design of a Java Virtual Machine. It comes with a subset of the Java 2 Platform, Standard Edition Java API and tools needed to provide a Java runtime environment. Like most other Free Java virtual machines, Kaffe uses GNU Classpath as its class library. Clean room design is the method of copying a design by reverse engineering and then recreating it without infringing any of the copyrights and trade secrets associated with the original design. ...

Kaffe is a lean, fast and portable virtual machine. When compared to the reference implementation of the JVM written by Sun Microsystems, Kaffe is significantly smaller; it thus appeals to embedded system developers. It comes with just-in-time compilers for many of the CPU architectures, and has been ported to more than 70 system platforms in total. It runs on devices ranging from embedded SuperH devices to zSeries mainframes, it will even run on a PlayStation 2. In general terms, a virtual machine in computer science is software that creates a virtualized environment between the computer platform and the end user in which the end user can operate software. ...
