The Duke and the Beastie - Improving OpenJDK support for FreeBSD
summary
One and a half years of sponsored work produces a production-grade OpenJDK port for FreeBSD maintained by a three-person team, with the FreeBSD ports tree now shipping JDK 25 as default (up from Java 8). Key engineering facts: build uses a boot JDK and sometimes an SSH-forwarding stub JDK to bootstrap; testing runs under JTreg test suite; CI uses GitHub Actions + QEMU emulated BSD hosts (slow, fragile). Upstreaming is ongoing and JCK conformance remains to be completed.
