Install on FreeBSD
Research Preview — not production supported
Eliya ships a FreeBSD build because no other vendor does — it's a signature of Asymm Systems' commitment to JVM infrastructure engineering. The FreeBSD build is honestly labelled as a Research Preview: one manual quarterly release, community-supported, no CVE SLA.
Read this first
- No commercial support. No SLA. Issues via GitHub only.
- Security patches best-effort — target one quarterly manual rebuild per CPU window.
- Not published to SDKman. Install via direct download only.
- Built on top of the battleblow OpenJDK BSD port — community patches that live outside upstream OpenJDK.
- If your workload needs enterprise JDK support on FreeBSD, use the FreeBSD ports tree's
openjdk25package instead. Eliya FreeBSD is a curiosity / research build.

Known caveats
- AWT / Swing / JavaFX are unsupported on FreeBSD (as with most JDK BSD ports).
- Some HotSpot features (ZGC, Shenandoah) may have platform-specific caveats from the BSD patchset. Test before relying.
- JFR works.
jcmdworks. Standard server workloads (Netty, Spring Boot, gRPC) work.
