> We got the rule consequence exception which is caused by ConcurrentModificationException. This happened when we import the payments for the consumers in the batch, and one of the consumer failed.  The rule is defined in the decision table in Guvnor. The source for the rule is attached. It's just a simple eligibility check. 
> Please investigate the issue. Thanks.
