BTW: We (the GraalVM team) maintain a full-blown LLVM bitcode runtime that can be embedded in Spring or any other JVM application and compiled to native: https://github.com/oracle/graal/tree/master/sulong
As Thomas mentioned, we continue our mission to run programs faster and more efficiently. So yes, the GraalVM Docker images are still maintained and now include images with the new GraalVM 25 release.
