+1 for this.
It makes senses we don't generate the transition serialVersionUID for
the exception.

Hi,
Currently when use wsdl2java, by default the generated exception class
has a serialVersionUID field which use the timestamp when generate the
code, also we have another flag useFQCNForFaultSerialVersionUID which
generate serialVersionUID based on hashcode of the fully qualified class
name of the Exception.
The serialVersionUID generally doesn't matter when we use typical way to
do webservice invocation which use jaxb to do marshall/unmarsall,
however, for some scenario customer need use java serialization to
serialize/deserialize the auto-generated Exception object(like using jms
or rmi to pass object directly), and generally they won't generate the
code once and use the same copy of generated code everywhere, customer
just have same copy of wsdl file and generate the code when they need
use it, this cause the problem that the serialVersionUID is different
timestamp, so even though it's actually same exception class, they can't
use java serialization.
I know that customer may change the wsdl before generate code each time,
but IMHO java serialVersionUID to provide a chance that try it best to
match the serialize/deserialize even between different java class
version(a new filed added doesn't matter), so how about we make
useFQCNForFaultSerialVersionUID as default behavior, if the qualified
class name not change, then generate same serialVersionUID, it's make it
easier to use generated exception with java serialization.
