### Are you willing to submit a pull request?

No

Start with org.netbeans.modules.remote.impl.fs.RemoteFileSystem.java at line 1295 and trace the call through VCSFileProxy.java into LocalHistory.java. Reproduce the failure by opening a remote file on Windows 11 with NetBeans 27, then verify that the file opens without the reported NullPointerException and that the relevant remote-file behavior remains functional.
