Project Lilliput - Compact Object Headers


This presentation will discuss the OpenJDK project Lilliput, which aims to reduce object header sizes, and with it, memory and CPU consumption of the HotSpot JVM. We will start with a short overview of the status-quo in HotSpot, and explain the goals and motivations. We will then give an overview of what has been achieved so far - 64-bits-headers -, and look ahead at our plans for the future - 32-bits-headers - and our vision on how to achieve this, and which technical challenges we need to solve.
