UntrustedURLConnectionIOException invoking Exception invoking a web service with https and requireClientCertificate

Issue

• We are currently calling a web service, which is a SOAP service with Transport binding and has <sp:HttpsToken RequireClientCertificate="true"></sp:HttpsToken>, this service is hosted on IIS server, when trying to connect from CXF , we are getting

Caused by: org.apache.cxf.transport.http.UntrustedURLConnectionIOException: UntrustedURLConnectionIOException invoking https://<host>:<port>/Service1.svc: RequireClientCertificate is 
set, but no local certificates were negotiated.  Is the server set to ask for client authorization?

• We tried to dig into more details and we found this article and a bug, which is related, https://issues.apache.org/jira/browse/CXF-5525.
