The Maxine virtual machine is an open source virtual machine that is developed at the University of Manchester.[1] It was formerly developed by Sun Microsystems Laboratories,[2] since renamed Oracle Labs. The emphasis in Maxine's software architecture is on modular design and code reuse for flexibility, configurability, and productivity for industrial and academic virtual machine researchers. It is one of a growing number of Java virtual machines written entirely in Java in a meta-circular style. Examples include Squawk and Jikes RVM.
Architecture
The Maxine VM is characterized internally by aggressive use of advanced language features in Java 1.5 and 1.6, by modular subsystems coordinated through Java interfaces, and by the absence of an interpreter.
Compatibility
Maxine is plug compatible with an unmodified Java Development Kit (JDK). Maxine can be developed, built, and run in standard Java integrated development environments (IDEs), including NetBeans, Eclipse, and IntelliJ IDEA.
Systems programming in Java
A secondary goal of the project is to develop methods and tools for "systems programming in Java". Compiler extensions, configured in VM source code using Java annotations, allow use, with no performance penalty, of low-level operations otherwise disallowed in Java.
The Maxine Inspector
Specialized debugging support for the Maxine VM is provided by the Maxine Inspector: a companion tool that acts as a combined object, class, and method browser, and as a machine- and bytecode-level debugger.[3] The Inspector runs out-of-process, needs no active VM support, and leverages code shared with the VM for specialized developer services.
History
Maxine was created by Bernd Mathiske at Sun Labs in early 2005. He led its development among a growing team until late 2008 when he left Sun Microsystems and handed the project over to Doug Simon who had been the first engineer to join it. Doug Simon continued in this role throughout the acquisition of Sun by Oracle Corporation.
The Maxine inspector was created by Bernd Mathiske at Sun Labs in 2006. Further development was handed over to Michael Van De Vanter in 2007.
Oracle continued development of Maxine until the release of Maxine 2.0.[4] The University of Manchester is developing Maxine as of release 2.1.[5]
