Hi Paul,
It turns out, JAXB runtime does not provide correct information
on the score attribute in this (unfortunate xs:anyAttribute) case.
I am not sure this could be fixed easily, but you can try using the following
JSON configuration as a workaround:
return new JSONJAXBContext(
JSONConfiguration
.mapped()
.attributeAsElement("score")
.arrays("release-group")
// comment this out, if you want to get string "50" instead of number 50
.nonStrings("score")
.build(),
"org.musicbrainz.mmd2");
in the initJsonContext method.
Which gives me:
{"release-group-list":{"release-group":[{"score":50},{"score":50},{"score":50},{"score":50},{"score":50}]}}
HTH,
~Jakub
