Java virtual machine

The Java virtual machine is a Virtual machine that runs Java byte codes, the codes produced by a Java compiler or compilers from other languages which produce this code.

The specification for this virtual machine are published in book form and [html] and anybody is allowed to write an implementation of it. The preface states We intend that this specification should sufficiently document the Java Virtual Machine to make possible compatible clean-room implementations. Sun provides tests which verify the proper operation of implementations of the Java Virtual Machine. . [www.kaffe.org] shows an example of a group of developers having done this.
