[ http://issues.apache.org/jira/browse/DERBY-1517?page=comments#action_12421669 ] Kathey Marsden commented on DERBY-1517: ---------------------------------------
I want to understand the user impact of this issue with and without the patch for DERBY-528. Do I understand the description correctly that if DERBY-528 patch is applied, 10.2 clients do not work with 10.1 servers but without the DERBY-528 patch there is no impact on users?
