Three years ago (or so) I did experimental project named J-SMILE to prove that it is possible. Main idea of it is simple – to create as small as possible Java (Virtual Machine) that can be attached to compiled Java bytecode (.class files). Physically J-SMILE VM is an .exe file of size 200k. These 200k…
