I would suggest to not put @XmlRootElement annotation in GemsMetadata,
and instead put a @XmlTransient annotation. I'm not sure however why it
worked before - I would have expected both the old Geotk and the new
Apache SIS objects to behave the same way in this regards. Maybe the
change in behaviour is related to the change in JDK version used, since
they come with different JAXB versions.
