title: JAXB un/marshalling: Is there a difference between using arrays and lists?
body: <p>I'm fairly new to JAXB and am eager to learn more about it. 
  What I've noticed is that when marshalling, the XML representation of the objects from an array and list are the identical. </p>
  
  <p>What I'm interested in finding out is how JAXB treats the two data structures when un/marshalling and if it's better to standardize it to use one over the other? 
  If so, what is the difference between the two (performance-wise, etc.)? 
  Also, what should I consider when choosing a container for my objects? </p>
  
  <p>Any information will be appreciated. Thank you!</p>
