Hi,

Versions:
Scala: org.scala-lang:scala-library:2.12.0-RC1
Jackson-Scala: com.fasterxml.jackson.module:jackson-module-scala_2.12.0-M5:2.8.2

Error is

java.lang.NoSuchMethodError: scala.Predef$._refArrayOps([Ljava/lang/Object;)[Ljava/lang/Object;

I've now released 2.8.3 and 2.7.8 for 2.12.0-RC1. If you really need me to backport an older version let me know.

[cowtowncoder]

I would be -1 for earlier versions, although if someone really really wanted 2.6 version, that might be negotiable.
