ZeroTurnaround announced the release of JavaRebel 2.0, a JVM plugin that enables Java developers to see  changes to their code immediately, without the need for application or container restarts.

Two weeks ago, JavaRebel 1.0 won a JOLT Productivity Award for its role in cutting development time and  development team costs - recognition of the significant productivity gains that current customers are  reporting. "We're hearing that teams are saving an average of 10-40 minutes per developer, per day, in time  otherwise wasted on application restarts", said ZeroTurnaround marketing captain, David Booth, "Using time  saved and developer salaries to calculate ROI, we're talking about thousands of dollars in savings, per year,  from each member of the team using JavaRebel in their development." With JavaRebel 2.0's expanded feature  set, easy installation, and dramatically improved performance, ZeroTurnaround looks to build upon the success  of the first version.

While the cost savings are beneficial in any economic climate, developers report results of another nature.  "We're hearing that the folks who used to look with envy at this feature in dynamic languages like Ruby and  Python, are feeling much more comfortable with their Java applications now", mentions ZeroTurnaround founder,  Jevgeni Kabanov, "they're enjoying the quick feedback and the incremental development techniques that flow  naturally from a lightweight coding style like this."

JavaRebel 2.0 supports:
* Changes to method bodies
* Changes to class structure, including adding methods, fields, constructors, changing/adding annotations,  and changing interfaces
* Changes to configurations in Spring, Guice, Wicket, Stripes, Tapestry 4, and Struts2, with an open API for  adding further support
* All major JVMs and containers
* Exploded and Packaged Development practices here.
