C++ interpreter
C++ interpreter

“Sun also released its older C++ based interpreter to help the porting effort”
The C++ interpreter is actually the newer of the two. The template interpreter is the original and is written entirely in assembler, so a port to a new platform involves (amongst other things) writing individual implementations of each of the 200 or so bytecodes. The C++ interpreter has these bytecode implementations in C++ so it's much easier to bring up on a new platform. It was originally written to port Java 1.4.2 to ia64 (ia64 assembly is “special”).

AFAIK cacao supports annotations. I asked twisti about this some time back. Debugging (JMVTI) and split verification is what it lacks. However I am working on the latter for my diploma thesis :)
