JsonQueryServlet does not return multi-value properties

From the mailing list:

I'm trying to get back a multivalued property from the JSON Query Servlet, but it appears that that doesn't work. Here's what I did:

curl -Ftitle="some title text" -Ftext="some body text content" \
-Ftest="1" -Ftest="2" http://admin:admin@localhost:8080/some/new/content

That posts successfully, and I can view it at http://localhost:8080/some/new/content.json and see that test is ["1","2"]. If I try to find it with JQS though at

http://localhost:8080/some.query.json?queryType=xpath&statement=/jcr:root/some/new/*&property=title&property=test

The title property is correctly displayed, but test is shown as "". Is this a known issue, or should I open a Jira?
