Synapse: Exception from PayloadHelper.setXMLPayload

[Wright, Peter]

Hi,

I have a JMSListener that receives a JMS message containing a path to an XML 
file on a REST server.
A Class Mediator gets the REST-path from the message and http-GETs the XML file.
Now I want to set the XML file content as the payload of the message that is 
then passed further
to a SOAP service.

I get the file content OK in my class mediator, but get an error when trying to 
set
the content as the XML payload.

Java Code:
InputStream istr = getFileFromRestServer(path);
String xmlstr = convertStreamToString(istr);
OMElement xmlElem = AXIOMUtil.stringToOM(xmlstr);
PayloadHelper.setXMLPayload(mc, xmlElem);

Error Message:
java.util.ConcurrentModificationException: The current node has been removed 
using a method other than Iterator#remove()

Any ideas?
The xmlstr and xmlElem look fine when I print them to STDOUT.

I initially tried to set the payload as follows:
mc.getEnvelope().getBody().getFirstElement().setText(xmlstr);
instead of using setXMLPayload.
This worked, but all the xml start tags "<" in the payload are encoded as "&lt;"

Thanks
Peter
