Description

2.12.1
Works

        <simple>"${body.subOrderName}Endpoint"</simple>

Fails

         <groovy>"${request.body.subOrderName}Endpoint"</groovy>

2.11.1
Works

        <simple>"${body.subOrderName}Endpoint"</simple>

Works

        <groovy>"${request.body.subOrderName}Endpoint"</groovy>

*Fails by returning a previous calls result for subOrderName.
To reproduce you must make several calls in a timely manner with different bean data (OGNL/subOrderName).

Route:

...
<setHeader headerName="RSSX_ORDER_ROUTING_SLIP">
<groovy>return "${request.body.subOrderName}Endpoint"</groovy>
</setHeader>
<!-- Route the order by the routing slip header -->
<routingSlip>
<header>RSSX_ORDER_ROUTING_SLIP</header>
</routingSlip>
...

Log:
1st execution
Before set header: UpdatePortIn

After set header: RSSX_ORDER_ROUTING_SLIP=UpdatePortInEndpoint

2nd execution (in a timely manner – exposing a LRU Cache issue?)
Before set header: ResellerAddSubscriberPortIn
After set header: RSSX_ORDER_ROUTING_SLIP=UpdatePortInEndpoint

Same logic works in 2.11.1

Additionally this does not appear OGNL related:
I just ran into the case where

<setHeader headerName="RSSX_ORDER_ROUTING_SLIP">
        <groovy>"${request.body.getSubOrderName()}Endpoint"</groovy>
      </setHeader>

returns the cached subOrderName from the previous transaction

So this appears to be isolated to the <groovy> component changes (LRU Cache?) that were introduced in 2.12.1
