java - Infinite loop while using Files.newDirectoryStream -

i wrote test zip files in dummy directory:

public void compressfiletoziptest() throws ioexception{      try (directorystream<path> stream = files.newdirectorystream(             paths.get("src", "test", "resources", "dummy", "files"), new filesfilter())){          (path entry: stream) {             path dst = entry.getparent().resolve(entry.getfilename().tostring() + ".zip");             boolean succeed = filesutility.compresstozip(entry, dst);             assert.asserttrue("failed create destination file", succeed);             try(zipfile zipfile = new zipfile(dst.tofile())){                 assert.asserttrue("failed 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);     } } 

the test worked until our build team changed underlining nas storage, lead infinite loop while streaming directory , writing it.

i glad if 1 can explain issue (i assume it's related paths iterator implementation).
