I have generated client stub from WSDL, which has the following fragment:
-----------------------------------------------------------------------
    public double calc(java.lang.String string_1, double double_2,
double double_3) throws java.rmi.RemoteException{
        if (super.cachedEndpoint == null) {
            throw new org.apache.axis.NoEndPointException();
        }
        org.apache.axis.client.Call call = createCall();
        javax.xml.namespace.QName p0QName = new
javax.xml.namespace.QName("", "String_1");
        call.addParameter(p0QName, new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "string"),
java.lang.String.class, javax.xml.rpc.ParameterMode.IN);
        javax.xml.namespace.QName p1QName = new
javax.xml.namespace.QName("", "double_2");
        call.addParameter(p1QName, new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "double"),
double.class, javax.xml.rpc.ParameterMode.IN);
        javax.xml.namespace.QName p2QName = new
javax.xml.namespace.QName("", "double_3");
        call.addParameter(p2QName, new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema", "double"),
double.class, javax.xml.rpc.ParameterMode.IN);
        call.setReturnType(new
javax.xml.namespace.QName("http://www.w3.org/2001/XMLSchema",
"double"));
        call.setUseSOAPAction(true);
        call.setSOAPActionURI("");
        call.setOperationStyle("rpc");
        call.setOperationName(new
javax.xml.namespace.QName("http://hello.org/wsdl", "calc"));

        Object resp = call.invoke(new Object[] {string_1, new
Double(double_2), new Double(double_3)});

        if (resp instanceof java.rmi.RemoteException) {
            throw (java.rmi.RemoteException)resp;
        }
        else {
            try {
                return ((Double) resp).doubleValue();
            } catch (java.lang.Exception e) {
                return ((Double)
org.apache.axis.utils.JavaUtils.convert(resp,
double.class)).doubleValue();
            }
        }
    }
-----------------------------------------------------------------------
So far so good, but when this "calc" method is called and the server
side throws an AxisFault, the "resp" object is null instead of AxisFault
object. Since null is not an instance of RemoteException, it causes a 
NullPointerException in line: 

 return ((Double)org.apache.axis.utils.JavaUtils.convert
(resp,double.class)).doubleValue();

Exception stacktrace and axis.log are too long to insert in this report,
but I can send them if needed.
