This change fixes "JDK-8383867: File.getCanonicalPath drops backslash from UNC path with directory junctions" when running Java in Windows from a network shared folder, like "\\MyNetworkShare\jdk\bin\java.exe", JVM drops a backslash when creating a canonical path if the path goes through a reparse point - it turns to "\MyNetworkShare\jdk\bin\java.exe" (the only backslash in the front).
I extended `test\jdk\java\io\File\GetCanonicalPath.java` test with the reparse point scenario. The test fails before the fix, and passes with the fix. --------- - [x] I confirm that I make this contribution in accordance with the [OpenJDK Interim AI Policy](https://openjdk.org/legal/ai). ------------- Commit messages: - minor comment - correct UNC path format during canonicalization Changes: https://git.openjdk.org/jdk/pull/31192/files Webrev: https://webrevs.openjdk.org/?repo=jdk&pr=31192&range=00 Issue: https://bugs.openjdk.org/browse/JDK-8383867 Stats: 33 lines in 2 files changed: 22 ins; 0 del; 11 mod Patch: https://git.openjdk.org/jdk/pull/31192.diff Fetch: git fetch https://git.openjdk.org/jdk.git pull/31192/head:pull/31192 PR: https://git.openjdk.org/jdk/pull/31192
