 A simplified Java virtual machine written in Go language. One aim is to learn JVM specification in depth and try to understand the behind-the-scene behaviour when a Java program runs. This VM can be used for the educational purpose, for example, for a course about how to design a runtime for a language with the complete specification.
 
 I only refer to "Java Virtual Machine Specification" and then look into how we should design one.
