Opened https://bugs.openjdk.org/browse/JDK-8319708 8319708: Assertion 'fsetenv didn't work' in jdk tier4 tests after 8295159 on Linux aarch64 RHEL9.3 Unfortunately , the shared libs loaded by the JDK native C code (and the dependencies of those libs) are not covered at all, so it is unclear to me what exactly caused the issue. Maybe some sound-related lib on RHEL ? ------------- PR Comment: https://git.openjdk.org/jdk/pull/10661#issuecomment-1803816232
