Great finding! Indeed the following is a quick reproducer for any java8 version -- openjdk8 302/312, icedtea8 and even Oracle JDK8 202: systemd-run --wait -t -p InaccessiblePaths=/sys /usr/lib64/jvm/openjdk8/bin/java -version So far couldn't reproduce with openjdk11 and FWIW it does not reproduce on aarch64. _______________________________________________ pld-devel-en mailing list pld-devel-en@lists.pld-linux.org http://lists.pld-linux.org/mailman/listinfo/pld-devel-en
