java - 使用 Files.newDirectoryStream 时的无限循环

Question

我写了一些测试，在一些虚拟目录中压缩文件：

public void compressFileToZipTest() throws IOException{

    try (DirectoryStream<Path> stream = Files.newDirectoryStream(
            Paths.get("src", "test", "resources", "dummy", "files"), new FilesFilter())){

        for (Path entry: stream) {
            Path dst = entry.getParent().resolve(entry.getFileName().toString() + ".zip");
            boolean succeed = FilesUtility.compressToZip(entry, dst);
            Assert.assertTrue("Failed to create destination file", succeed);
            try(ZipFile zipFile = new ZipFile(dst.toFile())){
                Assert.assertTrue("Failed to compress file size", Files.size(entry) > Files.size(dst));
            }
            dst.toFile().deleteOnExit();
        }
    }
}


private static final class FilesFilter implements DirectoryStream.Filter<Path>{
    @Override
    public boolean accept(Path entry) throws IOException {
        return !Files.isDirectory(entry);
    }
}

测试运行良好，直到我们的构建团队更改了下划线的 NAS 存储，这导致从目录流式传输并写入它时出现无限循环。

如果有人能解释这个问题，我会很高兴（我假设它与路径迭代器实现有关）。
