Lukyt is a small JVM made in Lua supporting Java 1.4. It's main advantage is to currently have a very small startup time and use way much less memory.
How to use?
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.
