Project Leyden

The primary goal of this Project is to address the long-term pain points of Java’s slow startup time, slow time to peak performance, and large footprint.

Leyden will address these pain points by introducing a concept of static images to the Java Platform, and to the JDK.

• A static image is a standalone program, derived from an application, which runs that application — and no other.

• A static image is a closed world with respect to the classes that it can load: At run time it cannot load classes from outside the image, nor can it create classes dynamically.

This Project is sponsored by the HotSpot and Core Libraries Groups.
