JRJC throwing JSONException sporadically

[Yarin Benado]

It appears like on few REST calls (createIssue() for example), JRJC will receive an empty string for a result and will throw the exception below. Calling the REST method again works though, so I have to make the following hack:

int tries = 0;                                           
do {                                                     
    try {                                                
        basicIssue = issueClient.createIssue(in).claim();
        tries = 1000000;                                 
    } catch (Exception e) {                              
        tries++;                                         
        System.err.println("Failed creating issue!");    
        e.printStackTrace();                             
    }                                                    
} while (tries <= 3);

Hi Yarin,

Also you may need to report this to https://ecosystem.atlassian.net/browse/JRJC so our developers can take a look at it.

Cheers,

Omar

It appears like JRJC 2.0.0 is too immature. Ported the code back to JRJC 1.0.0 and it no weird async things happen.

[Aleksander Mierzwicki]

I've replied in https://ecosystem.atlassian.net/browse/JRJC-146 - we need more details to track this issue. The 2.0.0-m16 should be quite stable (not many changes are planed for 2.0 release).

P.S. Next time please add jira-rest-java-client tag, so we'll get notified about new question related to JRJC.

Using JRJC 2.0.0-m8 and 2.0.0-m9. same behavior
