This PR proposes to improve the `TestBufferStackStress` and `TestBufferStackStress2` tests by removing an unnecessary `@build` tag and reducing the required work of `TestBufferStackStress`.
The `TestBufferStackStress` is also proposed to be removed from the ProblemList as the underlying issue (https://bugs.openjdk.org/browse/JDK-8350455) has been fixed. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - Improve TestBufferStackStress* Changes: https://git.openjdk.org/jdk/pull/30835/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=30835&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8373298 Stats: 9 lines in 3 files changed: 0 ins; 4 del; 5 mod Patch: https://git.openjdk.org/jdk/pull/30835.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/30835/head:pull/30835 PR: https://git.openjdk.org/jdk/pull/30835
