Please review this rather trivial fix to not use `nio` in `CgroupUtil`, part of the JDK's Metrics API. The primary motivating factor is that it allows one to use the JDK's version of `Metrics` in GraalVM. See the bug for details as to why this is needed.
Testing: - [x] GraalVM builds with/without the fix and the reproducer (fails before/works after) - [x] `jdk/internal/platform` jtreg tests on Linux x86_64 (cgv1). - [ ] GHA - still running ------------- Commit messages: - 8314940: Use of NIO in JDKs Metrics implementation causes issues in GraalVM Changes: https://git.openjdk.org/jdk/pull/15416/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=15416&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8314940 Stats: 29 lines in 1 file changed: 11 ins; 14 del; 4 mod Patch: https://git.openjdk.org/jdk/pull/15416.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/15416/head:pull/15416 PR: https://git.openjdk.org/jdk/pull/15416
