Looks like this issue: https://bugs.openjdk.org/browse/JDK-8274122
Could also be related to thius issue(although this one was backported to jdk8): https://bugs.openjdk.org/browse/JDK-8347740

Notes:

- The failing tests happened on Windows Server 2025.
- Sophia's passing grinder ran on Windows Server 2022: https://ci.adoptium.net/job/Grinder/17997/
- Upstream issue [JDK-8274122](https://bugs.openjdk.org/browse/JDK-8274122):
- Has the same symptom.
- Was not backported to JDK8
- Is related to Windows 11.

Start with java/io/File/createTempFile/SpecialTempFile.java, especially the failing assertion at SpecialTempFile.java:76, and inspect the attached output and test archive. Rerun the Grinder job while comparing Windows Server 2022 and 2025, then read JDK-8274122 and JDK-8347740. Done means the test correctly handles the Windows 2025 behavior and passes without losing its intended coverage.
