I added a SerializationTest. The test contains a helper that can
generate serialization files for XMLGregorianCalendar and Duration. I've
created such files for jdk6,7,8 and 9, and manually run the test, that
is, read them back with JDK6, 7, 8 and 9. The test worked fine. In the
JDK9(or 10 in the future) repo and for an auto-run, it would use the
current JDK9/10 build and test against JDK6, 7, 8 and 9. Past JDK10, we
could consider add serialization files for JDK10.
The new fields did not affect serialization compatibility. The above
tests passed with/without the new fields being transient. But I added
transient since it's the right thing to do.
Adding fields is a compatible change in accordance with Java Object
