Leave GZIPOutputStream open is dangerous as it leads to native memory leak.
Use try-finally to make sure stream is always closed

private final LocalByteArray response = new LocalByteArray();
private final static String HEALTHY_RESPONSE = "Exporter is Healthy.";
private final Charset UTF_8 = Charset.forName("UTF-8");
