Initial testing seems to indicate that this works like a charm.
1) Include the JRbel SDK as a dependency in your project
<dependency>
<groupId>org.zeroturnaround</groupId>
<artifactId>javarebel-sdk</artifactId>
<version>2.0.2</version>
</dependency>
2) Add the following class to your project and invoke it's register() method at
application startup time (of course you’ll have to adapt the class to your own
environment)

Voila—instant reloading of Cayenne models.
