Lukyt is a JVM made in Lua supporting Java 1.2. It's main advantage is to currently have a very small startup time and use way much less memory.

Roadmap

The JVM itself can be used by any program and is independent from the command-line program.

The command line program allows to execute classes. You can print an help message with lua lukyt.lua --help

To launch the HelloWorld test, you can do:

lua lukyt.lua --classpath=test HelloWorld

which will give the same result as:

java -cp test HelloWorld

On my computer, the HelloWorld example used maximum 2.5MB while on the same computer, the OpenJDK's JVM used maximum 13MB.
