Geoffrey De Smet updated DROOLS-1171:

> Key: DROOLS-1171
> URL: https://issues.jboss.org/browse/DROOLS-1171
> Project: Drools
> Issue Type: Bug
> Components: core engine
> Reporter: Geoffrey De Smet
> Assignee: Mario Fusco
>
> To reproduce, add this VM option: -Ddrools.dialect.java.compiler=NATIVE
> when running for example XStreamXmlSolverFactoryTest in optaplanner-core (but any DRL, in drools-compiler's tests should suffice already).
> I get this stacktrace:
