Extending a Java virtual machine to dynamic object oriented languages There are two common approaches to implement a virtual machine (VM) for a dynamic object oriented language. On the one hand it can be implemented in a C like language for best performance and maximum control over the resulting executable. On the other hand it can be implemented in a language such as Java that allows for higher level abstractions. These abstractions such as proper object oriented modularization automatic memory management or interfaces are missing in C like languages but they can simplify the implementation of prevalent but complex concepts in VMs such as garbage collectors (GCs) or just in time compilers (JITs). Yet the implementation of a dynamic object oriented language in Java eventually results in two VMs on top of each other (double stack) which impedes performance. For statically typed languages the Maxine VM solves this problem; it is written in Java but can be executed without a Java virtual machine (JVM). However it is currently not possible to execute dynamic object oriented languages in Maxine. This work presents an approach to bringing object models and execution models of dynamic object oriented languages to the Maxine VM and the application of this approach to Squeak Smalltalk. The representation of objects in and the execution of dynamic object oriented languages pose certain challenges to the Maxine VM that lacks certain variation points necessary to enable an effortless and straightforward implementation of dynamic object oriented languages execution models. The implementation of Squeak Smalltalk in Maxine as a feasibility study is to unveil such missing variation points.
