> The 'src/main/resources/rules/Sample.drl' contains an adapted version of the default Drools Eclipse plugin sample rule. As you can see, the rule uses Conditional Named Consequence construct. Although the rule is a bit strange (the issue actuallty popped up while debugging another issue) it does show different behaviour between ReteOO and PHREAK, where in this case PHREAK actually goes into an infinitie-loop, even though 'no-loop' has been defined on the "Hello World" rule.
> To run the sample using ReteOO:
> - mvn -Preteoo exec:java
> The (correct) output is:
> Hello World
> Goodbye cruel world
> To run the sample using PHREAK
> - mvn -Pphreak exec:java
> The incorrect output is:
> Hello, I'm here!
> Hello World
> Goodbye cruel world
> Goodbye cruel world
> Goodbye cruel world
> Goodbye cruel world
> Goodbye cruel world
> {infinite loop}
> Note that the PHREAK run also prints "Hello, I'm here!" and ReteOO doesn't (because the activation of that rule is canceled when the Message is updated with a new message and status).
