title: method finalize and exceptions
body: <p>I don't understand very well when an exception is ignored by the GC when it reclaims from the memory an object.</p>
  
  <p>If I have a <code>try/catch</code> into a finalize method I see it is always executed... so which are the cases where the exception is not thrown?</p>
  
  <p>Thanks.</p>
