JIRA-REST-JAVA - Error MalformedInputException on creating issue

Question

I'm using jira-rest-java-client-core and jira-rest-java-client-api (2.0.0-m31) wih maven. GET an issue works fine but i've a problem when I try to create one.

JiraRestClientFactory factory = new AsynchronousJiraRestClientFactory();
JiraRestClient jiraRestClient = factory.createWithBasicHttpAuthentication(URI.create("https://jira_host"), username, password);
IssueRestClient client = jiraRestClient.getIssueClient();
IssueInputBuilder issueBuilder = new IssueInputBuilder("TEST", 1L, "Summary Test");
IssueInput issueInput = issueBuilder.build();
BasicIssue issue = client.createIssue(issueInput).claim();

and the error :

org.apache.http.impl.nio.client.LoggingAsyncRequestExecutor exception

Have you got an idea to resolve that ?
