Changeset: cd136fcd Author: Jiangli Zhou <jianglizhou@google.com> Date: 2023-10-09 20:05:51 +0000 URL: https://git.openjdk.org/leyden/commit/cd136fcd70b3011120b4c5f0e1fe7643f7f2f0... Delay the initialization of 'jarFileSystem' field in JavaHome. The earlier https://github.com/jianglizhou/jdk/commit/a4de3f83b33145a46878b37dd254795065... change in ProcessImpl.java causes JavaHome class initialization occur early before the module system initialization. That in turn causes the loading of the "Jar" provider happen before the module system initialization. When running on a hermetic Jar, the system fails to start due to "java.nio.file.ProviderNotFoundException: Provider "jar" not found". This change delays the initialization of JavaHome.jarFileSystem. It's no longer initialized during JavaHome <clinit>. The initialization of JavaHome.jarFileSystem now happens when the system first tries to access a hermetic JAR packaged JDK resource/property file. ! src/java.base/share/classes/jdk/internal/misc/JavaHome.java Changeset: df76caf7 Author: Jiangli Zhou <jianglizhou@google.com> Date: 2023-10-19 13:32:03 +0000 URL: https://git.openjdk.org/leyden/commit/df76caf70de46fb1295fe962a007c74dcb8abd... Check `isHermetic` for `isHermetic()` as `jarFileSystem` may not initialized yet when `isHermetic()` is called. This bug was causing java.nio.file.FileSystemException when loading conf/security/java.security. ! src/java.base/share/classes/jdk/internal/misc/JavaHome.java
