[jboss-jira] [JBoss JIRA] (DROOLS-4089) EvaluatedExpression not well resolved with JIT during race

[vincent palau (Jira)]

     [ https://issues.jboss.org/browse/DROOLS-4089?page=com.atlassian.jira.plugin.system.issuetabpanels:all-tabpanel ]

vincent palau updated DROOLS-4089:
----------------------------------
    Description: 
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

 !debugging-1.png|full! 

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.
