DecisionTable incorrectly parsed with 5.2.0.CR1

5.2.0.CR1 creates incorrect drl from decision table. With 5.1.0.M1 the drl for the same decision table is correct.

Wrong DRL from 5.2.0.CR1:
rule "ProcessState"
salience 65522
ruleflow-group "CompleteSubOrder"
activation-group "ProcessState"
when
$m:ModifiedMarker(processState==null, state ==null)
$s:SubOrder
then
$m.setIsModified(true);
$s.setProcessState(ProcessState.CREATED);

end

Correct DRL with 5.1.0.M1:
rule "ProcessState"
salience 65522
ruleflow-group "CompleteSubOrder"
activation-group "ProcessState"
when
$m:ModifiedMarker()
$s:SubOrder(processState==null, state ==null)
then
$m.setIsModified(true);
$s.setProcessState(ProcessState.CREATED);

end

The difference is that the constraints are put to $m instead of putting them to $s.
The attached jpg contains the decision table snippet.

The behaviour in 5.2.0.CR1 is the same for all decision tables in my project and prevents me from upgrading to newer drools versions.
