Adds :z to the shared /tmp volume mounts in these container tests so the SELinux relabel happens automatically. Without it, under SELinux enforcing the container can't write to the bind-mounted dir and the tests fail with "/tmp/started Permission denied" on cgroups-v2 hosts.
:z matches the existing pattern in TestJcmd.java. Verified on OL9 aarch64 and OL9 x64 cgroups-v2 and all 3 tests pass. Note: there's also a separate host-side cpu cgroup delegation issue on some aarch64 hosts that affects TestLimitsUpdating; that's a setup/infra fix, tracked separately from this test change --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - 8324871: Several container tests fail with java.io.tmpdir directory does not exist on linux-aarch64 cgroups-v2 Changes: https://git.openjdk.org/jdk/pull/31890/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31890&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8324871 Stats: 3 lines in 3 files changed: 0 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/31890.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31890/head:pull/31890 PR: https://git.openjdk.org/jdk/pull/31890
