Welcome to the CRaC Project!
The CRaC (Coordinated Restore at Checkpoint) Project researches coordination of Java programs with mechanisms to checkpoint (make an image of, snapshot) a Java instance while it is executing. Restoring from the image could be a solution to some of the problems with the start-up and warm-up times. The primary aim of the Project is to develop a new standard mechanism-agnostic API to notify Java programs about the checkpoint and restore events. Other research activities will include, but will not be limited to, integration with existing checkpoint/restore mechanisms and development of new ones, changes to JVM and JDK to make images smaller and ensure they are correct.

Making changes to the code
Minor changes (build failures fixes, typos, ...) can be pushed directly. Pull Request is a recommended way since it will check the build succeeds.
For new features and major changes, use Skara:
- create a JBS issue in JDK project with Affected and Fix Version equal to
- make a Pull Request following suggestions from the Skara bot (Change must not contain extraneous whitespace, Commit message must refer to an issue, Change must be properly reviewed)
