Generated Exceptions differ each generation

[yoadey]

Description:
The Java files which are generated by the AntCodegenTask for Exceptions differ each generation in the serialVersionUID.
This is especially bothering if the gradle cache should be used, wich requires a fixed input. Also, the objects may not be deserialized again if the SerialVersionUID changes each time.

Steps to reproduce:
Create a WSDL with a wsdl:fault element, e.g:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:tns="http://www.example.org/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="ExampleModule" targetNamespace="http://www.example.org/">
    <wsdl:types>
        <xsd:schema targetNamespace="http://www.example.org/">
            <xsd:element name="getSolutionById">
                <xsd:complexType>

                        <xsd:element name="in" type="xsd:string"/>
                    </xsd:sequence>

Generate it again, the serialVersionUID changes

More info
I've checked and found the corresponding issue in the file AxisServiceBasedMultiLanguageEmitter.java in line 1055, where the System.currentTimeMillis() is used for the serialVersionUID.
A hash based on the className and the parameters would probably be better.
