Dynamically assigning partnerLink EPR fails

The dyamic EPR assignment operations from the ODE User Guide do not work. Specifically the cases for a Simple URL and a wrapped soap:address fail. This same operation performs correctly in ODE 1.3.4 in Tomcat 6.0

These are the relevant portions of my BPEL spec:
<bpel:partnerLinks>
<bpel:partnerLink name="SafariFusionOssLink"
partnerLinkType="sfWsdl:FusionOssLinkType"
partnerRole="fusionOssService"
initializePartnerRole="yes"/>
</bpel:partnerLinks>

<bpel:assign name="createFusionCreateRqst">
<bpel:copy>
<bpel:from>
<bpel:literal>http://172.16.150.174:8080/safariap/OSS/FusionOss</bpel:literal>
</bpel:from>
<bpel:to partnerLink="SafariFusionOssLink"/>
</bpel:copy>
</bpel:assign>

<bpel:invoke name="sendFusionCreateRqst"
partnerLink="SafariFusionOssLink"
portType="sfWsdl:FusionOssPort"
operation="create"
inputVariable="sndCreateRqst"
outputVariable="sndEditResp" />

From the WSDL:
<plnk:partnerLinkType name="FusionOssLinkType">
<plnk:role name="fusionOssService" portType="tns:FusionOssPort"/>
</plnk:partnerLinkType>

<wsdl:service name="FusionOss">
<wsdl:port name="FusionOssSoap" binding="tns:FusionOssBinding">
<soap:address location="http://localhost:8080/safariap/OSS/FusionOss"/> <!-- Note the different address -->
</wsdl:port>
</wsdl:service>

When the invoke operation is performed the following exceptions are reported:
18:26:32,954 ERROR [DispatchImpl] Cannot dispatch message
