You are right List<List<String>> is wrong but you'll get the same error
if you use List<String> instead (which is legal). @MatrixParam is meant
to be the same as @QueryParam. It is retrieved from the URI, not the
body entity. At this point I am fairly sure that this is a Jersey bug.
PS: You can read more about @MatrixParam here:
