Hi Could I suggest you use a JMS topic, which each of the consumers being a durable shared consumer where you use a separate consumer subscription for each filter.
The issue I think you are hitting is that with a JMS Queue the is only a one core created and with message groups per group only on consumer is selected so that if the group for the filter you have is assigned to the other consumer you hit this issue. Sure there could be done to make this work feel free to contribute :), but I would try the above, for the use case I imagine you may have.
