Generic security error from thrid party web service endpoint

Issue

I'm invoking a third party endpoint using a JAX-WS client, and I'm getting the following error:

javax.xml.ws.soap.SOAPFaultException: Error al comprobar la seguridad del mensaje.
    at org.jboss.ws.core.jaxws.SOAPFaultHelperJAXWS.getSOAPFaultException(SOAPFaultHelperJAXWS.java:85)
    at org.jboss.ws.core.jaxws.binding.SOAP11BindingJAXWS.throwFaultException(SOAP11BindingJAXWS.java:107)
    at org.jboss.ws.core.CommonSOAPBinding.unbindResponseMessage(CommonSOAPBinding.java:558)

    at org.jboss.ws.core.jaxws.client.ClientProxy.invoke(ClientProxy.java:157)
    at $Proxy585.invokeEndpoint(Unknown Source)

Note that the message in the SOAPFaultException can be any general security-related message. It is pulled from the SOAP fault returned from the server endpoint.
