Client wsdl giving the issue while invoking it in Jdeveloper 12c (12.2.1.4) OSB Business service end

My client has provided the one way message type wsdl which contains the Fault element in inside the Operation along with Input elements and fault element is refering the another common fault wsdl. We are unable to invoke the wsdl in Jdeveloper using OSB business service end. but if we remove the fault element from wsdl then its not giving any issues.

But as per my client requirement we sould not modify the their end point wsdl and use it as it is.

Jdeveloper is not supporting this wsdl and throwing the error that Out put element is expected instead of Fault element .if any one can have the pointers please help me.
