Did you try to use failover[1] ?

I have a use case that requires a certain endpoint to be re-used. Lets say
the re-usable endpoint is called router1.
The flow below causes a blockage on my route and leads to camel throwing
exception.
consumerEndPoint -> router1 -> someIntermediateEndPoint -> router1`->
someProviderEndpoint ........
This flow is an InOut exchange flow. What is happening is that, because the
first message passes through router1 and it is still waiting for a response,
router1` will wait forever. I think camel throws the exception below

Loadbalancer is not resolving this as it still ends up sending to same
router.
See my camel snippets below:
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";
trace="true">
<route>
<from uri="nmr:consumerEndPoint"/>
<loadBalance ref="roundRobinRef">
<to uri="vm:router1"/>
<to uri="vm:router2"/>
</loadBalance>
</route>
</camelContext>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";
trace="true">
<route>
<from uri="nmr:someIntermediateEndPoint "/>
<loadBalance ref="roundRobinRef">
<to uri="vm:router1"/>
<to uri="vm:router2"/>
</loadBalance>
</route>
</camelContext>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";
trace="true">
<route>
<from uri="nmr:someProviderEndPoint"/>
<to uri="mock:whatever"/>
</route>
</camelContext>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";
trace="true">
<route>
<from uri="vm:router1"/>
<bean ref="router1ProcessorRecipientList" method="route"/>
</route>
</camelContext>
<camelContext id="camel" xmlns="http://camel.apache.org/schema/spring";
trace="true">
<route>
<from uri="vm:router2"/>
<bean ref="router2ProcessorRecipientList" method="route"/>
</route>
</camelContext>
What EIP would be the most appropriate for this scenario?
kr.
