This PR addresses [JDK-8370578](https://bugs.openjdk.org/browse/JDK-8370578)
Under certain circumstances, OpenJDK on macOS maps the hsperf segment private instead of shared; one of those cases is hit during the tier1 tests, which test for that. This PR allows for shared or private mapping; the purpose of the intermittently failing test is to test System.map implementation, not JDK internals. ------------- Commit messages: - allow private or shared hsperf segment Changes: https://git.openjdk.org/jdk/pull/28025/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=28025&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8370578 Stats: 5 lines in 1 file changed: 2 ins; 0 del; 3 mod Patch: https://git.openjdk.org/jdk/pull/28025.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/28025/head:pull/28025 PR: https://git.openjdk.org/jdk/pull/28025
