Oracle SOA Suite 10g to 11g Migration - Web service Invocation issue,Invalid URI "urn:#NewOperation"

Oracle SOA Suite 10g to 11g Migration  - Web service Invocation issue,Invalid URI "urn:#NewOperation":

The web service invocation has failed after migrating the web services to 11g with the following error

Caused By: oracle.j2ee.ws.common.addressing.api.AddressingException: Invalid URI "urn:#NewOperation" in Addressing element Action.

But the same web service was working properly in 10g.

To overcome this we have changed the soapaction "urn:#NewOperation" to empty string in web service WSDL manually and it resolved the issue.
