Java implementation of a... JVM?

Question

Some time ago I found the MJVM project. Sadly, this project has been abandoned by it author (I asked Igor via email).

I wonder if there is a (continued) open source project of a full implementation of a JVM in Java like this one.

By "full", I mean, not only to emulate mobile devices.

Answer 1

Jikes RVM is a JVM written in Java, used for research and kept under active development.

Answer 2

JNode is a JVM + operating system written in Java that runs one a bare x86 PC or virtual. The project's SVN has been pretty inactive of late (roughly the last 6 months), but I believe there is activity in the GIT mirrors for the project.
