## Notes on http-kit server
33-
**GraalVM-CE-Java8-20.0.0** is preferred when using `http-kit` as a server.
34-
The native image compilation succeed with both **GraalVM-CE-Java11-20.0.0** and **GraalVM-CE-Java8-20.0.0** in this example project, however in a fully fledged application **GraalVM-CE-Java11-20.0.0** fails to compile.
35-
**GraalVM-CE-Java8-20.0.0** succeeds in both cases.
