Messages being stopped hby the idempotent-receiver-router aren't processed by the forwarding-catch-all-strategy. For instance, in the following config:

<inbound>
<jms:inbound-endpoint queue="orders">
<message-properties-transformer scope="outbound">
<add-message-property key="orderId" value="#[header:INBOUND:orderId]"/>
</message-properties-transformer>
</jms:inbound-endpoint>
<idempotent-receiver-router idExpression="#[header:OUTBOUND:orderId]"/>
<forwarding-catch-all-strategy>
<vm:outbound-endpoint path="duplicate.orders" exchange-pattern="one-way"/>
</forwarding-catch-all-strategy>
</inbound>

A duplicate message is caught by the idempotent-receiver-router but never forwarded to the "duplicate.orders" queue.
