Rule is not fired in decision server when migrating from BRMS 6.1 to 6.2

Issue

• After migrating from BRMS 6.1 to 6.2, rules are not fired in decision server (kie-server). The REST request is like this:

<batch-execution>
 <insert out-identifier="cust" return-object="true">
    <com.sample.Customer>
      <age>38</age>
    </com.sample.Customer>
    </insert>  
     <fire-all-rules out-identifier="firedActivations"/>
</batch-execution>
