> Key: DROOLS-856
> URL: https://issues.jboss.org/browse/DROOLS-856
> Project: Drools
> Issue Type: Bug
> Affects Versions: 6.2.0.Final
> Environment: Works fine on 6.1.0.Final, but breaks at runtime with 6.2.0.Final - compilation with 6.2.0.Final is OK, just runtime breaks

> This is affecting at least the {{matches}} operator but could it also have further impacts, up to you to evaluate =) I hope is helpful case. I will attach reproducer.
> Assume the following rules :
> {code}
> rule "color measure wrap"
> salience 1000
> no-loop
> when
> $m : Measurement( id == "color" )
> then
> AWrapper aw = new AWrapper($m);
> retract($m);
> insert(aw);
> end
> rule "wrapper matches"
> salience 999
> no-loop
> when
> AWrapper ( $val : m.dataVal() , $val matches "#......" )
> then
> System.out.println("I've matched an actual color, "+$val);
> end
> {code}
> This passes the rule-compilation stage OK on both 6.1.0.Final and 6.2.0.Final of the kie-maven-plugin for instance, but breaks at runtime with 6.2.0.Final with the following stacktrace:
