Abstract
A method of performing a processing task in a data processing apparatus is provided that reduces memory usage of the processing task. According to this method a Virtual Machine performs the steps of accessing platform-neutral program code in a function repository, executing the processing task on the Virtual Machine, and analysing at a current execution point, on a function-by-function basis, which functions in the function repository are inactive functions. The Virtual Machine performs software-based unloading from the function repository of at least a portion of platform-neutral program code corresponding to one or more inactive functions. A corresponding virtual machine and data processing apparatus are also provided.
