title: Unable to create session for handle using JavaRTO API
body: <p>I've been following the tutorial for Solace JavaRTO [low latency] </p>

  <p>However, it seems that when I get to the part where you create the session for handle I run into the following error.</p>

  <p>Without the actual source I am unable to debug further to try and locate the issue but it sounds like some parameter might be incorrect or null. However, I have been able to successfully connect, publish and subscribe to Solace using the same params with the normal Java API.</p>
  
  <p>Does anyone know if there are any properties that are specific to the low latency JavaRTO API or anything else that might be causing this issue?</p>
