title: how to detect if a bundle is completely loaded in osgi container?
body: <p>is there any kind of event listeners like the ones in BundleEvent Class for detecting if a bundle is completely loaded and available for requests? </p>
  
  <p>I made a search and all i could find is <a href="https://stackoverflow.com/questions/5879040/how-to-detect-if-running-in-osgi-container">this</a></p>
  
  <p>which doesnt use event listeners and means that i need to check manually or periodically (i didnt test that piece of code by the way.</p>
  
  <p>are there any events like BundleEvent.STARTING for a load operation? or we need to implement one by ourselves (if possible) ?</p>
