Update 17-MAY-2011: just verified if it's still a problem in 5.2.0.CR1-SNAPSHOT and it is.
To reproduce:
- Open org.drools.planner.examples.cloudbalancing.domain.CloudAssignment
- Comment out public int getMinimalCpuPower()
- Run org.drools.planner.examples.app.DroolsPlannerExamplesApp, click button cloud computing
