>          Issue Type: Bug
>      Security Level: Public(Everyone can see) 
>          Components: drools-planner
>    Affects Versions: 5.3.0.CR1
>            Reporter: Cédric Schaller
>            Assignee: Geoffrey De Smet
>             Fix For: 5.4.0.Beta1

>   Original Estimate: 5 minutes

> The following code: 
> {code:java}
>             Method propertyGetter = propertyDescriptor.getReadMethod();
>             if (propertyGetter.isAnnotationPresent(PlanningVariable.class)) {
> {code}
> in method {{processPropertyAnnotations()}} assumes that properties always have getters. However, the method {{getReadMethod()}} might indeed return {{null}} if the property is write-only, as explained in the JavaBeans(TM) Specification 1.01 Final Release. A null-check should therefore be added in order to prevent NullPointerExceptions.
