Running a CRaC Java application on Raspberry Pi - UPDATE

CRaC (Coordinated Restore at Checkpoint) now works on Raspberry Pi thanks to two key updates: the new Raspberry Pi OS based on Debian Bookworm (with kernel 6.1.0 including CONFIG_CHECKPOINT_RESTORE=y) and Zulu builds of OpenJDK 17 and 21 with CRaC support. A step-by-step walkthrough covers installing SDKMAN, Zulu 21 CRaC build, and Maven, then running a Jetty example app, creating a checkpoint, and restoring from it. Both Zulu 17.0.8 and Zulu 21 work flawlessly on ARM64 hardware, enabling fast JVM startup times on inexpensive Raspberry Pi hardware.
