JAVA Version For APEX : Error in integration to Sendinblue : |System.CalloutException: java.lang.RuntimeException: Could not generate DH keypair

Hi All,

We are trying to integrate Salesforce to Sendinblue and the error we are getting in HTTP call out is

Sendinblue support team asked us for JAVA version that APEX uses as this issue is accouring with JAVA version 7 and above.

"Hello,

Is it be possible to check the Java version used by APEX and Eclipse. As per our technical team's understanding the issue is with Java version 7 onwards.

Please check the links below for further informations.

Following is the code.

Thanks a lot.

public with sharing class MySforceHttpCallOut {

String endPoint = 'https://api.sendinblue.com/v2.0/campaign/1' ;

public void fetchDataFromRemote(){
   performAction('GET');    
}
  
public void performAction(String method){

             HttpRequest req = new HttpRequest();
            req.setEndpoint(endPoint);
             req.setHeader('api-key', 'GAVE MY API KEY HERE');
             req.setHeader('Content-Type', 'application/json');
             
             req.setMethod(method);
            
             System.debug(req);

             Http http = new Http();
             HTTPResponse res = http.send(req);   -> Failing HERE
            System.debug( res.getBody());
             Map<String,String> responseMap =   (Map<String,String>)JSON.deSerialize(res.getBody(),Map<String,String>.class);
              
              System.debug(responseMap);
              
  }

Salesforce presently runs on JDK7 (which is why you see the 2048-bit DH key issue), and will gradually be upgraded to JDK8 through a series of patches, hopefully by Summer '15.

A workaround mentiooned by R&D in one of the discussions is to de-preference DH ciphers on your server side. Please be noted that Salesforce should be upgraded to JDK8 wiith the Summer '15 release. Here's the release schedule: https://trust.salesforce.com/trust/maintenance/
