FileUtils.writeStringToFile does not close() stream

FileUtils.writeStringToFile() method does not close the OutputStream.  This can lead to running out of file descriptors, inability to write to the file a second time (Windows), and unpredictable file contents (Unix).

    public static void writeStringToFile(final File file, final String data, final Charset encoding,
                                         final boolean append) throws IOException {
        try (OutputStream out = openOutputStream(file, append))

{             IOUtils.write(data, out, encoding);         }

    }

 

The stream is closed in version 2.5, but not in 2.6.  It may have been introduced on the following commit:
