Wait, GraalVM is implemented in Java? Does that mean to run it you need another JVM to run it on top of? That sounds stupid... Maybe you need another VM just t

GraalVM is the regular HotspotVM integrated with the GraalVM compiler (which is normally AOT compiled as a native library, but can be run as a JAR); it also supports tooling with the ability to compile code targeting the JVM to a native executable, as well as leveraging AOT compilation itself. https://www.graalvm.org/22.3/reference-manual/native-image/ https://www.graalvm.org/22.3/reference-manual/native-image/

  Lots of languages and run times are self hosting today. There are several Java VMs out there. This is but one of them. Its been demonstrated that it's not that hard to create an operational Java VM from scratch. A straightforward interpreter can do the job. The VM doesn't change the source language.

  The same way the c++ compilers, runtimes and standard libraries are implemented in c++.
