Question
I am running a program that will generate some load against a url and further consume the same URL using RestTemplate.
The url that I am hitting will return me a simple string Hello World as the response.
Below is the program that will generate the load against the url.

Russianpublic class ShellbareboneLnP {
public static void main(String[] args) {
try {
// create thread pool with given size
ExecutorService service = Executors.newFixedThreadPool(threads);
// queue some tasks
long startTime = System.currentTimeMillis();
long endTime = startTime + (durationOfRun * 60 * 1000);
for (int i = 0; i < threads; i++) {
service.submit(new ShellBareboneTask(endTime));
}
service.shutdown();
service.awaitTermination(Long.MAX_VALUE, TimeUnit.DAYS);
} catch (InterruptedException e) {
LOG.warn("Threw a Interrupted Exception in" + CNAME + ".ShellbareboneLnP: boss told me to stop...Not my fault!!");
} catch (Exception e) {
LOG.warn("Threw a Exception in" + CNAME + e);
} finally {
}
}
}
class ShellBareboneTask implements Runnable {
private static final Logger LOG = Logger.getLogger(ShellBareboneTask.class.getName());
public static ConcurrentHashMap<String, AtomicInteger> exceptionMap = new ConcurrentHashMap<String, AtomicInteger>();
private final long endTime;
/**
* Constructor to pass the values
*
* @param durationOfRun
*/
public ShellBareboneTask(long endTime) {
this.endTime = endTime;
}
@Override
public void run() {
try {
RestTemplate restTemplate = new RestTemplate();
while (System.currentTimeMillis() <= endTime) {
PerformanceTimer timer = PerformanceTimer.getInstance();
restTemplate.getForObject("some_url", String.class);
timer.getDuration();
}
} catch (Exception e) {
handleException(e.getCause() != null ? e.getCause().toString() : e.toString());
e.printStackTrace();
}
}
}
And every time, I am getting the below exception after some time when the program is running. I am not sure what is causing these exceptions. Can anyone help me here?

Solution
java.lang.IllegalArgumentException: No matching constant for [0] at org.springframework.http.HttpStatus.valueOf(HttpStatus.java:426)
the exception message indicates your server side code generated a response with status code: 0 which is invalid.
can you post your server side code?
OTHER TIPS
I got the same error while working on Spring version 3, after upgrading to 4.2.2 it got resolved.
I recently had a similar problem.
I've found a solution by changing my ClientHttpRequest to HttpComponentsClient.
Here's what I've done:
restTemplate.setRequestFactory(new HttpComponentsClientHttpRequestFactory());
Hope it helps
