             Summary: "Contains" is not null-safe with executable model
                 Key: DROOLS-5315
                 URL: https://issues.redhat.com/browse/DROOLS-5315
             Project: Drools
          Issue Type: Bug
          Components: core engine
    Affects Versions: 7.37.0.Final
            Reporter: Matteo Casalino
            Assignee: Mario Fusco
         Attachments: null-contains-exec-model.zip

When executing rules with executable model, _contains _ constraints are not null-safe, whereas they are in DRL mode

Example of DRL that exhibits the behavior:


{noformat}
    rule "contains constraint"
    when Pojo(integerList contains 3)
    then
    end
{noformat}


Error:


{noformat}
    java.lang.RuntimeException: java.lang.RuntimeException: java.lang.NullPointerException
    
    	at org.drools.modelcompiler.constraints.ConstraintEvaluator.evaluate(ConstraintEvaluator.java:95)
    	at org.drools.modelcompiler.constraints.LambdaConstraint.isAllowed(LambdaConstraint.java:132)
    	at org.drools.core.reteoo.AlphaNode.assertObject(AlphaNode.java:139)
    	at org.drools.core.reteoo.SingleObjectSinkAdapter.propagateAssertObject(SingleObjectSinkAdapter.java:70)
    	at org.drools.core.reteoo.ObjectTypeNode.propagateAssert(ObjectTypeNode.java:329)
     ...

{noformat}


The example works fine when running without executable model.

The documentation is not explicit about whether _contains _ should be null safe or not, so we are unsure whether this is to be considered or not a regression.
