Is your feature request related to a problem?

CRIU checkpoint/restore doesn't work with Paper (due to segfaults + issues with JVM). This makes it impossible to snapshot a running server and restore it later.

Describe the solution you'd like.

Add support for CRaC. This would require implementing org.crac.Resource handlers to properly close resources (region files, network, session locks) before checkpoint and reopen them after restore. Spring Boot, Micronaut, and Quarkus have all added CRaC support with great results.

Describe alternatives you've considered.

• Raw CRIU - segfaults
• Podman - wraps CRIU
