title: Collections via MXBeans
body: <p>I need to define and implement an MXBean interface. One of the methods would return a Collection. This seems to be not supported by MXBeans. I get an OpenDataException saying "Cannot convert type: java.util.Collection". If I change it to List or Set then it works.</p>
  
  <p>I have not found any documentation saying that Collections are not supported and this is why I am asking you experts. Do I miss something ?</p>
