JRebel 3.5 — Open Source Galore

The last few months were very busy here at ZeroTurnaround HQ in the cold and gloomy Estonia. We wanted to deliver something awesome to our users, before we fully switch to working on the larger things planned for the 4.0. To that effect we decided to address some of the long standing requests as well as make some improvements to deliver better on our promise of “All changes reloaded, instantly!”. Whereas the previous major release focused mainly on the Java EE standards, this time we put our attention to supporting various Open Source frameworks and tools.

JRebel 3.1.1 "Oogle" Released

This minor release includes a score of improvements across the board. Among the most important is that the Google App Engine support is now out of the beta and Google Web Toolkit support has been substantially improved, and the only reason we still keep it in beta is because we don’t have a full automated test harness for it yet. We have also tested JRebel with Tomcat 7 and Jetty 7.1 and can now declare them officially supported. Beta support for serializing added fields has been added, but is still disabled by default. Please add -Drebel.serialization=true and let us know how it works for you. Also we worked some of our magic with AspectJ and Groovy, so those of you who had issues should definitely upgrade to this version. See full changelog for details, or grab the download!
