Virtualized runtime environments like Java Virtual Machine (JVM) or Microsoft .NET's Common Language Runtime (CLR) introduce additional challenges to real-time software development. Since applications for such environments are usually deployed in platform independent intermediate code, one issue is the timing of code transformation from intermediate code into native code. We have developed a solution for this problem, so that code transformation is suitable for real-time systems. It combines pre-compilation of intermediate code with the elimination of indirect references in native code. The gain of determinism comes with an increased application startup time. In this paper we present an optimization that utilizes an Ahead-of-Time compiler to reduce the startup time while keeping the real-time suitable timing behaviour. In an experiment we compare our approach with existing ones and demonstrate its benefits for certain application cases.
