title: JPA: which implementations support lazy loading outside transactions?
body: <p>EclipseLink can load lazy relationships in entities even after the entity manager that has created them is no longer available. With Hibernate <a href="http://softaria.com/2011/07/26/eclipselink-versus-hibernate/" rel="noreferrer">this doesn't work</a>, or at least didn't at the time of that post.</p>
  
  <p>What about other providers? OpenJPA and DataNucleus in particular?</p>
  
  <p>What are the downsides to this (except more complex implementation)?</p>
