Description

This is a new feature to batch camel messages.

	<bean id="groupMessageAggregationStrategy" class="org.apache.camel.processor.aggregate.GroupedMessageAggregationStrategy" />
	
    <route>
        <from uri="direct:order"/>
        <aggregate strategyRef="groupMessageAggregationStrategy" completionSize="500" completionTimeout="3000">
            <correlationExpression>
                <simple>${header[some.thing]}</simple>
            </correlationExpression>
			
            <to uri="direct:aggregatedOrders"/>
        </aggregate>
    </route>

    <route>
        <from uri="direct:aggregated"/>
  		<bean ref="externalResource" method="batchOrders"/>
		<split>
            <xpath>/invoice/lineItems</xpath>
			<to uri="mock:result" />
        </split>
    </route>

This is different from GroupedExchangeAggregationStrategy, because Splitter supports org.camel.Message.
