Running the latest `static-jdk` `bin/java` built from your branch fails for me as well: $ bin/java Error: failed , because bin/java: undefined symbol: JNI_CreateJavaVM I only took a quick look, but I think this looks like https://bugs.openjdk.org/browse/JDK-8339522 that I filed in September. $ nm bin/java | grep JNI_CreateJavaVM 000000000162733c t JNI_CreateJavaVM 0000000001626e75 t _ZL22JNI_CreateJavaVM_innerPP7JavaVM_PPvS2_ jianglizhou@leia:~/github/jdk_pull_20837/build/linux-x86_64-server-slowdebug/images/static-jdk$ nm -D bin/java | grep JNI_CreateJavaVM The VM dynamic symbols are not exported properly. This is related to the https://github.com/openjdk/jdk/pull/20837#discussion_r1744611776 discussion comment thread. ------------- PR Comment: https://git.openjdk.org/jdk/pull/20837#issuecomment-2436496612
