I am getting this exception when making an HTTPs call. It happens infrequently, presumably due to a time-out?

Exception in thread "Keep-Alive-Timer" java.lang.NoSuchMethodError: org.silvertunnel_ng.netlib.adapter.url.impl.net.http.KeepAliveCache.keySet()Ljava/util/concurrent/ConcurrentHashMap$KeySetView;
at org.silvertunnel_ng.netlib.adapter.url.impl.net.http.KeepAliveCache.run(KeepAliveCache.java:237)
at java.lang.Thread.run(Thread.java:745)

Here is the snippet of the code I am running:

             URL url = new URL( context, urlStr, handler );

            HttpURLConnection urlConnection = ( HttpURLConnection ) url.openConnection();
            urlConnection.setConnectTimeout( 15000 );

            urlConnection.connect();
            int responseCode = urlConnection.getResponseCode();
            if ( responseCode != 200 ) {

                return;

            }

            is = urlConnection.getInputStream();

            BufferedReader in = new BufferedReader(new InputStreamReader( is ));
            StringBuilder htmlSb =  new StringBuilder(  );
            String inputLine;

            while ((inputLine = in.readLine()) != null) {

                htmlSb.append( inputLine ).append("\n");
            }

            in.close();

            content = htmlSb.toString();

Hi Kali,

sorry for the late reply.

What JDK/JRE are you using?

this method should be provided by the Java-implementation.

regards Tobi

java -version
java version "1.7.0_40"
Java(TM) SE Runtime Environment (build 1.7.0_40-b40)
Java HotSpot(TM) 64-Bit Server VM (build 24.0-b55, mixed mode)

Hello Tobias,

Firstly thanks for creating the awesome library. However, I am getting the same error as above and from what I understand there is some problem with the code. @Kaii where you able to fix this? Please let me know!

Thanks,
Vinit

I realized that we need Java 1.8 , not 1.7. I haven't upgraded to 1.8 but have verified that it makes the problem go away. I just ignore the error and haven't seen any obvious problems (other than the error message)

Hi,
sorry for the late reply. I think I've found the problem. I fixed the code to use an Iterator instead of a foreach and now it should work flawlessly ;)

You can download the new SNAPSHOT Version 0.0.5 from SF or Maven.

Hi,

I tried using SNAPSHOT Version 0.0.5 from SF, but I am getting the following error :
java.lang.NoClassDefFoundError: org/spongycastle/jce/provider/BouncyCastleProvider

I have bouncycastle:bcprov-jdk14:132 in my buildpath. Is there any other dependency that I am missing?

Thanks,
Vinit

I was able to resolve the above issue. But when I am using SNAPSHOT Version 0.0.5 from SF, I am getting the following error :

It just hangs after this and does not make a connection. The same code was working fine with Version 0.0.3. However now with 0.0.3 as well I am getting the same error. Could you please tell me what might be wrong?

Thanks,
Vinit
