ws-addressing action header is stored with leading and trailing white space

When the headers are read in and stored in the context.inMessage.Header the value of the header elements contains new line characters. So for the SOAP message:

...
<soap:Header>
<wsa:Action>
http://x.com/TestMethod
</wsa:Action>
...

The action header contains a new line character at the beginning and end of the string. ie "\n http://x.com/TestMehod\n"

In the AddressInHandler.invoke method, the action is looked up to find an operation and it can't match anything because of the new line characters. In this line:
AddressingOperationInfo aop = AddressingOperationInfo.getOperationByInAction(service.getServiceInfo(), headers
.getAction());

the headers.getAction() returns the action value with new line characters.

They need to be stripped off somewhere along the way.
