Adaptation of HotSwapping for the Guidewire environment

Previously, University contractors developed a modification to the Java HotSpot TM VM that allows arbitrary changes to existing classes (hotswapping). The current status of this work is available under the GPL2, as published by the Free Software Foundation. Key Goals: - Improve the current hotswapping implementation with focus on stability and production use. - Port the hotswapping patch back to JDK 6. - Investigate ways to improve hotswapping with respect to Guidewire's needs and Guidewire's pre-existing technology.
