Good code marked as red in the latest versions of the plugin (ReactiveMongo's BSONDocument)

When using http://reactivemongo.org/ the BSONDocument constructor is marked red even though the code compiles. The code was not marked as error in the plugin version 0.39.848 but unfortunately that version doesn't seem to be fully compatible with 13.1.4.

I've created a ticket about this too at http://youtrack.jetbrains.com/issue/SCL-7404. The problem makes it next to impossible to use IDEA with the library.
