      Description

      If a glob contains a grouping with a single item that contains a slash, ex. "

      {a/b}

      ", then globStatus throws "Illegal file pattern: Unclosed group near index 2" – regardless of whether the path exists. However, if the glob set contains more than one item, ex. "

      {a/b,c}

      ", then it throws a NullPointerException from FileSystem.java:1277.

      1276: FileStatus[] files = globStatusInternal(new Path(filePattern), filter);
      1277: for (FileStatus file : files) {
      1278:   results.add(file);
      1279: }
      

      The method globStatusInternal can return null, so the iterator fails with the NPE.
