### What changes were proposed in this pull request? Replace hardcoded filename with `File.createTempFile()` in `testReloadMissingTrustStore` to ensure the temporary `trustStore` file is created in the same filesystem as the test working directory. ### Why are the changes needed? This change fixes a unit test bug. JDK 21's `UnixFileSystem.move()` uses atomic rename operations that fail when moving files across different mounted filesystems. The test creates a temporary file in `/tmp` and attempts to move it to the current directory. When these locations are on different partitions, the atomic move fails with a `testmissing.jks: Cross-device link` error because the `rename()` system call cannot move files across different filesystems. The fix ensures both temporary and target files are created in the same filesystem by eliminating the cross-filesystem move operation. ### Does this PR introduce _any_ user-facing change? No. ### How was this patch tested? Verified `ReloadingX509TrustManagerSuite` passes with both JDK 21 and JDK 17: `build/mvn -pl common/network-common -Dtest=ReloadingX509TrustManagerSuite test` ### Was this patch authored or co-authored using generative AI tooling?
