Jikes RMV (Open Source Java Virtual Machine)

[Kevin A. Burton]

(it looks like they have their own standard library impl.  Hopefully someone can
convince them to work with the GNU Classpath team.)

The Jikes^(TM) Research Virtual Machine (Jikes RVM) provides the academic and
research communities with a flexible open testbed to prototype new virtual
machine technologies and experiment with a large variety of design alternatives.

The virtual machine infrastructure in the Jikes RVM release was independently
developed over the last four years as part of the Jalapeño research project at
the IBM T.J. Watson Research Center.

The Jikes RVM runs on AIX^(TM)/PowerPC^(TM), Linux©/PowerPC and Linux/IA-32
platforms and includes state-of-the-art virtual machine technologies for dynamic
compilation, adaptive optimization, garbage collection, thread scheduling and
synchronization. A distinguishing characteristic of the Jikes RVM is that it is
implemented in the Java^(TM) programming language and is self-hosted i.e., its
Java code runs on itself without requiring a second virtual machine. In
contrast, almost all other virtual machines for the Java platform are either
written in native code (typically, C or C++) or written in the Java programming
language with a reliance on a second underlying virtual machine to execute its
Java code. A Java implementation provides ease of portability, and a seamless
integration of virtual machine and application resources such as objects,
threads, and operating-system interfaces.
