Java Dynamic Compilers

• Sun's HotSpot. See also their white paper and technical report "Mixed-mode Bytecode Execution".

• Overview of the IBM Java Just-in-Time Compiler.

• IBM's (so far experimental) Jalapeño project. (The Jikes RVM is now open source.)

• IBM's Quicksilver uses what they call quasi-static compilation to achieve most of the benefits of static and dynamic techniques. See their paper "Quicksilver: A Quasi-Static Compiler for Java".

• Microsoft Virtual Machine Overview.

• The OpenJIT project is an ongoing Java JIT compiler project as a collaborative effort between Tokyo Institute of Technology and Fujitsu Laboratory.

• LaTTe is an open-source Java Virtual Machine and Just-in-Time Compiler.

• JRockit is a server-side adaptive Java JIT. All code is compiled (no interpreter); hot code is re-compiled with a more aggressive compiler.

• Insignia's Jeode is a Java JIT compiler for a wide range of embedded systems.

• Kaffe is a cleanroom open source VM for embedded devices.
