- Jrebel is a commercial tool that also lets you replace bytecode in a running program without loss of state.

"Hot code replacement" is a Java VM feature. What makes JRebel useful is support for live reconfiguration of a gazillion Java frameworks (e.g. Hibernate, CDI, Spring etc) so you don't have to restart your server after changing some configuration annotations. It's expensive though and slows down startup so it's a tradeoff.
