httpcomponents's ssl connection results in socket is closed - ssl

Question

I am trying to get some data from webserver which works fine with http.
But when I try https(ssl connection), I get the exceptions like below.
I get the http status code 200 and response content length 2230 which is correct.
java.net.SocketException: Socket is closed
at sun.security.ssl.SSLSocketImpl.checkEOF(SSLSocketImpl.java:1483)
at sun.security.ssl.AppInputStream.read(AppInputStream.java:92)

My code is like below with apache httpcomponents httpclient(4.2.5) library.
try {
HttpPost httppost = new HttpPost(uri);
HttpHost targetHost = new HttpHost(HOST_NAME, HOST_PORT, PROTOCOL);
InputStreamEntity reqEntity = new InputStreamEntity(new ByteArrayInputStream(request), -1);
String contentType = TSPConstants.CONST_TSA_CONTENT_TYPE_TSREQUEST;
reqEntity.setContentType(contentType);
reqEntity.setChunked(true);
// It may be more appropriate to use FileEntity class in this particular
// instance but we are using a more generic InputStreamEntity to demonstrate
// the capability to stream out data from any arbitrary source
//
// FileEntity entity = new FileEntity(file, "binary/octet-stream");
httppost.setEntity(reqEntity);
//Authentication
httpclient.getCredentialsProvider().setCredentials(
new AuthScope(targetHost.getHostName(), targetHost.getPort()),
new UsernamePasswordCredentials(id, password));
// Create AuthCache instance
AuthCache authCache = new BasicAuthCache();
// Generate BASIC scheme object and add it to the local
// auth cache
BasicScheme basicAuth = new BasicScheme();
authCache.put(targetHost, basicAuth);
// Add AuthCache to the execution context
BasicHttpContext httpContext = new BasicHttpContext();
httpContext.setAttribute(ClientContext.AUTH_CACHE, authCache);
httpContext.setAttribute(ClientContext.COOKIE_STORE, cookieStore);
//SSL
SSLContext ctx = SSLContext.getInstance("TLS");
X509TrustManager tm = new X509TrustManager() {
public void checkClientTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public void checkServerTrusted(X509Certificate[] xcs, String string) throws CertificateException { }
public X509Certificate[] getAcceptedIssuers() {
return null;
}
};
ctx.init(null, new TrustManager[]{tm}, null);
SSLSocketFactory ssf = new SSLSocketFactory(ctx, SSLSocketFactory.ALLOW_ALL_HOSTNAME_VERIFIER);
Scheme sch = new Scheme("https", HOST_PORT, ssf);
httpclient.getConnectionManager().getSchemeRegistry().register(sch);
System.out.println("executing request " + httppost.getRequestLine());
httpclient.execute(httppost, httpContext);
HttpResponse response = send(request);
HttpEntity resEntity = response.getEntity();
System.out.println("----------------------------------------");
System.out.println(response.getStatusLine());
if (resEntity != null) {
System.out.println("Response content length: " + resEntity.getContentLength());
System.out.println("Chunked?: " + resEntity.isChunked());
}
EntityUtils.consume(resEntity);
resEntity.getContent()
} finally {
// When HttpClient instance is no longer needed,
// shut down the connection manager to ensure
// immediate deallocation of all system resources
httpclient.getConnectionManager().shutdown();
}

Basically the answer gave #Avner in the comment.
The problem (for me) was, that the response was closed before the entity was read.
I did something like this, which was wrong:
HttpEntity entity = null;
try (CloseableHttpResponse response = client.execute(request)) {
entity = response.getEntity();
}
read(entity);
The following worked:
try (CloseableHttpResponse response = client.execute(request)) {
HttpEntity entity = response.getEntity();
read(entity);
}
The maybe not so obvious part: The try-with-resources block in the first example closed the stream, before it was read.
