- Around line 81-84: Update the repository deletion flow around Files.walk in
GitVersionControlLocalFileStorage to use try-with-resources, ensuring the
returned stream is closed on both normal and exceptional completion while
preserving the reverse-order deletion behavior.

Oracle Java Files.walk API documentation stream must be closed try-with-resources
💡 Result:
Yes, the Stream returned by the Files.walk API must be closed using a try-with-resources statement or a similar control structure [1][2]. The official Oracle documentation explicitly states that Files.walk returns a stream that encapsulates one or more DirectoryStream objects [3]. Because these streams hold open file system resources (such as directory handles), they must be closed to ensure those resources are released promptly [1][3]. Failing to close the stream can lead to resource leaks and may eventually exhaust the operating system's file descriptor limits [4]. According to the API documentation, you should use the try-with-resources construct to ensure the stream's close method is invoked after operations are completed [1][2]. Example of correct usage: try (Stream stream = Files.walk(startPath)) { stream.filter(Files::isRegularFile).forEach(System.out::println); } catch (IOException e) { // Handle potential IO exceptions during stream opening or traversal } While most Java streams do not require manual closing, Streams backed by I/O channels—such as those returned by Files.walk or Files.lines—are important exceptions that necessitate this resource management [5].

Restore try-with-resources for Files.walk.
Files.walk(directoryPath) holds open directory resources. Close the stream on normal and exceptional completion to prevent file-descriptor exhaustion during repeated repository deletions.
