用例 CompressedClassSpaceSizeInJmapHeap.java & Test8028623.java 在 ptrace 权限为 true 的环境测试失败

在 github Actions 默认提供的 CI 运行环境中 ptrace 权限为 false，导致 CompressedClassSpaceSizeInJmapHeap.java & Test8028623.java 跳过了预期的测试环节，表现为测试通过。

Start with CompressedClassSpaceSizeInJmapHeap.java and Test8028623.java, then inspect how the GitHub Actions environment controls ptrace permissions. Reproduce the tests with ptrace enabled and disabled, and establish a test result that does not report skipped coverage as a successful run; confirm the behavior in both environments.
