> We recently moved from Drools 7.9.0 to 7.20.
> Some errors started appearing in ours tests when calling static methods in LHS drools.
> This started happening when all tests were run simultaneously.
> It seems the mvel JIT compiler kicks in and it incorrectly evaluates the property name:
> A simple call to {noformat}ValidationUtils.isNullOrEmpty(interestedPartyNumber){noformat} ends up with this kind of error:
> {noformat}
> "java.lang.RuntimeException: Unknown property 'nullOrEmpty' on class tech.stage.utils.cwr.model.PublisherRecord"
> {noformat}
> Debugging info:
> Related source-code: https://github.com/kiegroup/drools/blob/7.20.0.Final/drools-core/src/main/java/org/drools/core/rule/constraint/MvelConstraint.java#L489

> 1)  is the current evaluated property
> 2) Should be the right property of WriterRecord
> 3) Perhaps the expression which should be executed instead of invocations.get(0)
> We fixed that somehow disabling JIT with {noformat}ConstraintJittingThresholdOption{noformat}
> Is there any chance to this bug fixed?
> Do you need more info?
> Thanks in advance for your support.
