The `static-jdk` image is enough to run a simple HelloWorld java program; however it cannot yet run JTReg tests. The reason for this is, afaict, that the javac launcher is missing. I am planning to examine if it is possible to add a small shim `javac` launcher that calls the static `java` with the proper main class. (And similarly for the other launchers.) The goal here must, after all, be that we should be able to run the normal jtreg tests on the `static-jdk` image. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20837#issuecomment-2326445877 PR Comment: https://git.openjdk.org/jdk/pull/20837#issuecomment-2326452510
