Demo application for testing Play! framework performance issues.

How to run

git clone https://github.com/asolntsev/big-app.play.git
cd big-app.play
play run

How to trigger reloading classes

Modify file app/util/Util.java and replace Object with Integer
Refresh http://localhost:9000/ in browser
- Expected result: Play detects the change and reloads classes
- Actual result:
  - Play throws billion of errors trying to reload classes
  - Old classes still live in memory (Play memory leaks)
