> I have an operation with no arguments, only an implicit header with direction {{IN}}. Calling the operation fails:
> {code}
> javax.xml.ws.soap.SOAPFaultException: wrong number of arguments while invoking public java.util.List sample.ImplicitHeaderWithExtSoapHeaderINSampleTest$ImplicitHeaderSampleImplementation.operationWithNoArgs(com.sample.audit.Audit) with params [com.sample.audit.Audit@c19fbf, com.sample.audit.Audit@c19fbf].
> 	at org.apache.cxf.jaxws.JaxWsClientProxy.invoke(JaxWsClientProxy.java:159)
> {code}
> It works for operations with non-empty parameters and when the implicit header has direction INOUT.
> I'll attach a sample that demonstrates the issue.
> Thanks!
