QueryParam is a query attribute.. ?attr=value.. so it's ok to use that. I actually dont know what MatrixParam is, but the error you are getting is because a GET should not take in a body entity at all. I'll have to look up MatrixParam, but it seems as if that comes across like an entity body and Jersey is preventing that. But.. I thought a QueryParam is only a string value.. you have a List<List<String>> in there.. which would seem wrong to me as a QueryParam. I could be wrong.. I've only used it to get attr=value query params.

Subject: Re: [Jersey] Jersey thinks @MatrixParam is an entity
It turns out that if you replace @MatrixParam with @QueryParam the problem
magically goes away. I filed a new bug report:
