To be sure, I did a minimal build on Linux x86_64. I set `--with-jvm-features=minimal --with-jvm-variants=minimal` for this. This leads to `JVM_FEATURES_minimal='compiler1 minimal opt-size serialgc'` So no jvmti, to GCs except serialgc . Just C1, no C2. The 'opt-size' flag is set so the libjvm is compiled with size optimization (on Linux -Os). The other native libs (JDK native libs) still use the opt-flags they always use, as I thought. ------------- PR Comment: https://git.openjdk.org/jdk/pull/23563#issuecomment-2678301414
