[ https://issues.redhat.com/browse/DROOLS-5668?page=com.atlassian.jira.plug... ] Sylvain Lemoine commented on DROOLS-5668: ----------------------------------------- I push a bit further my investigations, seems due to the way tuple for  dormant activation are now fully serialized (A), and it takes part in the definition of the activationkey in dormantActivations. As (A) is not present in earliest 7.x serialized session, the following piece of code is not able to filter dormant activation: {code:java} RuleImpl rule = activation.getRule(); ActivationKey activationKey = PersisterHelper.hasNodeMemory( rtn ) ? PersisterHelper.createActivationKey( rule.getPackageName(), rule.getName(), activation.getTuple().toObjects(true)) : PersisterHelper.createActivationKey( rule.getPackageName(), rule.getName(), activation.getTuple() ); this.tuplesCache.put( activationKey, activation.getTuple() ); return !dormantActivations.contains(activationKey);{code}   -- This message was sent by Atlassian Jira (v7.13.8#713008)
