Hello everyone,
I have created a sample application which connect to site with GetMethod,
its working fine. Its also working fine when I tried with proxy, But when I
provided wrong proxy credentials then it hangs.
Have tried with enabled info logging and got it goes in infinite loop. there
are too many below statements.

Please let me know what is the issue ?
I'm using httpclient3.1.
My Sample code is:

package testjava;
import java.io.IOException;
import net.chambal.license.ProxyAuthentication;
import org.apache.commons.httpclient.HostConfiguration;
import org.apache.commons.httpclient.HttpClient;
import org.apache.commons.httpclient.MultiThreadedHttpConnectionManager;
import org.apache.commons.httpclient.auth.CredentialsProvider;
import org.apache.commons.httpclient.methods.GetMethod;
import org.apache.commons.httpclient.params.HttpConnectionManagerParams;
/**

public class LM {

HttpClient httpClient = new HttpClient(connectionManager);
HostConfiguration secureHostConfig = new HostConfiguration();
secureHostConfig.setHost("example.com", 443, "https");
httpClient.setHostConfiguration(secureHostConfig);
if (sAutoDetect.equalsIgnoreCase("true") == true) {
proxy = "";
port = "";
}

secureHostConfig.setProxy(proxy, Integer.parseInt(port));

ProxyAuthentication objProxyAuthentication = null;
objProxyAuthentication = new
ProxyAuthentication(user, pass, sDomain, proxy);
httpClient.getParams().setParameter(CredentialsProvider.PROVIDER,
objProxyAuthentication);
httpClient.getParams().setAuthenticationPreemptive(false);
}
}
}
method = new GetMethod("https://example.com";);
int statusCode = 0;
statusCode = httpClient.executeMethod(secureHostConfig, method);
method.releaseConnection();
connectionManager.closeIdleConnections(0);
} catch (Exception e) {
System.out.print(e.getStackTrace().toString());
}
}
}
Thanks in advance.

This is not unexpected. Please see the javadoc of the
CredentialsProvider interface.
http://hc.apache.org/httpclient-3.x/apidocs/org/apache/commons/httpclient/auth/CredentialsProvider.html
I strongly recommend to avoid using CredentialsProvider in HttpClient 3.x
