Java^TM and the Java^TM Virtual Machine

Definition, Verification, Validation

The book provides a high-level description, together with a mathematical and an experimental analysis, of Java and of the Java Virtual Machine (JVM), including a standard compiler of Java programs to JVM code and the security critical bytecode verifier component of the JVM. The description is structured into language layers and machine components. It comes with a natural executable refinement (written in AsmGofer and provided on CD-ROM) which can be used for testing code. The method developed for this purpose, using Abstract State Machines (ASMs), can be applied to other virtual machines and to other programming languages as well.

The target readers are practitioners—programmers, implementors, standardizers, lecturers, students—who need for their work a complete, and at the same time transparent definition, and an executable model, of the language, and of the virtual machine underlying its intended implementation.

The book is available in pdf format as Jbook.pdf. PDF documents can be read and printed with the Adobe Acrobat Reader. The Acrobat Reader 4.05 for Microsoft Windows, Linux, and Solaris Sparc can be found in the directory Archive.

Executable Models

Mircosoft Windows

The file Jbook.exe installs the executable models and the examples on the local machine. The setup program creates a folder with links to the corresponding machines.

The executable models can also be started directly from the CD without installing the software. For this purpose, the directory machinesWin contain executable files for the machines introduced in the book. The filenames of the corresponding files are listed in the following table:

Machine Filename of executable file With history feature

Java Machine java.exe javaH.exe

Compiler Machine compiler.exe

Trustful Machine trustful.exe trustfulH.exe

Defensive Machine defensive.exe defensiveH.exe

Diligent Machine diligent.exe diligentH.exe

Use either the Explorer and double click the file or take the command prompt and change to the directory machinesWin and enter the name of the file (with or without the extension .exe).

Unix based operating systems

Machine	Filename of executable file	With history feature
Java Machine	`java.exe`	`javaH.exe`
Compiler Machine	`compiler.exe`
Trustful Machine	`trustful.exe`	`trustfulH.exe`
Defensive Machine	`defensive.exe`	`defensiveH.exe`
Diligent Machine	`diligent.exe`	`diligentH.exe`

The CD contains precompiled binaries in the directory machines for Linux, Solaris Sparc, and cygwin. You have to build your own binary if your platform is not among them. The sources of AsmGofer can be found in the Archive directory. The file misc/INSTALL describes how to use the compiled binary with our machines.
In case you have Linux, Solaris Sparc, or cygwin, change to the directory machines and type the corresponding command listed in the following table:

Machine	Command	With history feature
Java Machine	`./java`	`./javaH`
Compiler Machine	`./compiler`
Trustful Machine	`./trustful`	`./trustfulH`
Defensive Machine	`./defensive`	`./defensiveH`
Diligent Machine	`./diligent`	`./diligentH`
