JavaRebel

This is pretty bitchin’:

JavaRebel is a JVM plugin (-javaagent) that enables to reload changes made to Java class files on-the-fly, saving developers the time that it takes to redeploy an application or perform a container restart. It is a generic solution that works for Java EE and Java standalone applications.

In addition to that we have released a JavaRebel plugin for Spring that allows reloading/reinjecting Spring dependencies on-the-fly without reloading the bean factory or application context. We have prepared a screencast that demonstrates the Spring plugin features. See the plugin installation manual for more details or just download it.

Then again I did that in C++ years ago.

Yay! Get here.
