create a fork under openjdk

[Jiangli Zhou]

Liam explored using CRIU for taking process snapshots for Javac in the
past. His finding (based on preliminary measurements) indicated the
image size could have a heavier impact on startup performance, and
worse startup time could be observed due to larger images. The
environment was a cloud build & testing environment.

We want to understand potential security issues associated with taking
and storing snapshots of live Java processes in production
environments.

Best,
Jiangli
