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);
