A java virtual machine written from scratch

Description

I wrote this JVM just for fun. It works - I had a webserver up running on it.

Features

• Simple switch-case interpreter
• Mark and sweep garbage collection algorithm

OpenJDK integration

It's painful to bind a nacked JVM to the OpenJDK standard library, because the OpenJDK is quite HotSpot VM specific.

I had to

• load some core classes by hand before loading the JDK (see src/jvm/VirtualMachine.cpp)
• implement sun.misc.Unsafe by hand

State

Inactive
