case class with dashes incorrectly deserialized

[maspwr]

I'm actually not sure what is going on here yet, but it appears as though vals with matching prefixes get deserialized in an incorrect order.

scala> case class Foo(bar: String, dummy: String, `bar-extension`: String)
defined class Foo

scala> implicit val fooFormat: JsonFormat[Foo] = jsonFormat3(Foo)
fooFormat: spray.json.JsonFormat[Foo] = spray.json.ProductFormatsInstances$$anon$3@3e219936

scala> val fooString = """{"bar": "param1", "dummy": "param2", "bar-extension": "param3"}"""
fooString: String = {"bar": "param1", "dummy": "param2", "bar-extension": "param3"}

scala> fooString.parseJson.convertTo[Foo]
res7: Foo = Foo(param1,param3,param2)

Whoops, that looks like a bad bug!
Thanks for reporting! We will have to look into this.

This seems to be a scala bug.

case class Data(a: String, b: String, `a-some`: String)
val m = Data("1", "2", "3")
assert(m.productIterator.mkString(", ") == "1, 2, 3")

Result: "1, [3, 2]" did not equal "1, [2, 3]"

@SimonAdameit interesting find. Have you looked for it at http://issues.scala-lang.org?
