2007.0 getCustomization doesn't work with WSDL 2_6_0

I have a java webservices job using Apache Axis 1.4 that retrieves the custom record "customizations" this works fine using the WSDL 2_5_0 in nestuite 2007.0 - but when I use the new WSDL 2_6_0 I just get a status "isSuccess" of "false" returned. My java code looks like this:

CustomizationType type = new CustomizationType(GetCustomizationType.customRecordType);
GetCustomizationResult result = netsuitePort.getCustomization(type);
Status status = result.getStatus();
if (status.isIsSuccess()) {
    ....
} else {
    ....
}

The SOAP stuff actually sent is as follows:
