Scala Plugin crashes

I already tried to invalidate the caches btw

Implicit parameters names printing is fixed. Fix will be available in next plugin version.
As for crash it's hard to say what's going on. As I can see from threaddump you have very big for comprehensions in your code, and probably we have exponent in our analyzer around such for comprehensions. So it would be great to investigate problem with problematic sources (minimized example?).

I'm assuming it has something to do with this piece of code, if this would seem insufficient I can put the whole project on github or something

  val file = Source.fromFile("conf/searchforms.conf").mkString
    val json = Json.parse(file)

    val configs = for (value <- json.as[JsObject].values.toList
      ;name = (value \\ "name")
      ;optionKeys = (value \\ "optionKeys")
      ;optionValues = (value \\ "optionValues")
      ;initialQueryKey = (value \\ "initialQueryKey")
      ;initialQueryValue = (value \\ "initialQueryValue")
      ;fileRoot = (value \\ "fileRoot")
      ;options = (Json.fromJson[List[String]](optionKeys(0)).get, Json.fromJson[List[String]](optionValues(0)).get).zipped.toList
      ;initialQuery = (Json.fromJson[String](initialQueryKey(0)).get, Json.fromJson[String](initialQueryValue(0)).get)
      ;mapping = Json.parse(esService.getMapping(Json.fromJson[String](name(0)).get)).as[JsObject]
      ;properties = (mapping \\ "properties"); fields = properties.head.as[JsObject].keys.toList
      ;documentTypeConfig = new DocumentTypeConfig(Json.fromJson[String](name(0)).get, options, initialQuery, fields, Json.fromJson[String](fileRoot(0)).get)
    ) yield documentTypeConfig

and the json file looks like this:

{
    "documentType" : {
        "name" : "zendnota",
        "optionKeys" : ["date", "klantnr", "ritnr", "drop"],
        "optionValues" : ["Datum", "Klant", "Rit", "Drop"],
        "initialQueryKey" : "date",
        "initialQueryValue" : "yyyy-mm-dd",
        "fileRoot": "/home/ZENDNOTA/"
    },
    "documentType" : {
        "name" : "factuur",
        "optionKeys" : ["date", "klantnr", "factuurnr", "barnr", "factuurtype"],
        "optionValues" : ["Datum", "Klant", "Factuur", "Bar", "Type"],
        "initialQueryKey" : "date",
        "initialQueryValue" : "yyyy-mm-dd",
        "fileRoot": "/home/FACTUUR/"
    },
    "documentType" : {
         "name" : "test",
         "optionKeys" : ["test", "test", "test", "test", "test"],
         "optionValues" : ["Test", "Test", "Test", "Test", "Test"],
         "initialQueryKey" : "test",
         "initialQueryValue" : "Test",
         "fileRoot": "/home/TEST"
    }
}

I just fixed your issue http://youtrack.jetbrains.com/issue/SCL-5945

Thanks!
I'm looking forward to the update

Try nightly http://confluence.jetbrains.com/display/SCA/Scala+Plugin+Nightly+Builds+for+Cardea. Next official update will not be very soon.
