Application Exeptions mapped to SOAP faults

Ok so we know that Application Exceptions can be mapped to SOAP faults.
However, I am wondering what happens if they are not mapped?

answer from IBM...

http://www.ibm.com/developerworks/webservices/library/ws-jaxws-faults/index.html

What about unmodeled faults?

What happens when an unmodeled fault occurs? For example, what happens when the service above throws an exception other than sample2.fault.Fault (for instance, NullPointerException)? What happens on the client? The answer to that depends on the messaging protocol. For instance, when communicating via SOAP/HTTP, the server-side SOAP engine creates a SOAP message containing a SOAP fault (see Listing 9) with information relevant to the problem in the faultcode and faultstring fields. Because a SOAP fault is returned to the client, JAX-WS has defined an exception named SOAPFaultException. When the service throws an unmodeled fault, the client receives a SOAPFaultException.

javax.xml.ws.soap.SOAPFaultException is a protocol-specific exception. It extends javax.xml.ws.ProtocolException. JAX-WS defines another extension of ProtocolException: javax.xml.ws.http.HTTPException for the XML/HTTP communication channel. Those are the only standardized bindings defined for WSDL. For other bindings, assume the binding provider defines other extensions of ProtocolException, one for each new binding.
