title: Talend tRestClient Consume REST API with 1 header
body: <p>I'm trying to call a simple 'Hello World' REST API via the <strong>GET</strong> verb. The API is only expecting one HTTP Header, <strong>Accept application/json</strong> which i've set in the Advanced Settings>HTTP Headers of my <strong>tRestClient</strong> component. However, looking at the code tab, Talend seems to automatically create another entry for the contents of the Accept Type dropdown. When i run I’m getting <strong>HTTP 406 Not Acceptable</strong> back because the API is not expecting 2 headers. </p>
  
  <p>I've tested this API with other software and it responds correctly so it must be down to Talend configuration. Anybody know a way around this or had a similar issue they've resolved?</p>
  
  <p>I have screenshots but unfortunately they're being blocked by my firewall at work.</p>
  
  <p>Thanks</p>
