title: Redeploy alternatives to JRebel
body: <p>JRebel allows for newly compiled code to be redeployed without restarting the application.  I am wondering if there are any alternative (free?).  The  <a href="http://zeroturnaround.com/jrebel/faq/#3" rel="noreferrer">FAQ</a> page answers this question, but I am sure it's biased towards JRebel.  This question was asked a year ago on this site, but I am bringing it back up to see if anyone has any new information.</p>
  
  <p>On a side note, I really like JRebel, but if there is a free alternative, I am willing to try it.</p>
  
  <p>One additional note, I am working on an open source project, and they offer free one year licenses to people who can prove they are on an open source project.  Which works great for me (www.kuali.org), but I won't be on that project forever.</p>
