A lazy developer approach: Building a JVM with third party software

The development of a complete Java Virtual Machine (JVM) implementation is a tedious process which involves knowl-edge in different areas: garbage collection, just in time com-pilation, interpretation, file parsing, data structures, etc. The result is that developing its own virtual machine re-quires a considerable amount of man/year. In this paper we show that one can implement a JVM with third party software and with performance comparable to industrial and top open-source JVMs. Our proof-of-concept implementa-tion uses existing versions of a garbage collector, a just in time compiler, and the base library, and is robust enough to execute complex Java applications such as the OSGi Felix implementation and the Tomcat servlet container
