> We actually still have some test failures in the Scala 2.12 build. There seem to be two types. First are that some tests fail with "TaskNotSerializable" because some code construct now captures a reference to scalatest's AssertionHelper. Example:
> {code:java}
> - LegacyAccumulatorWrapper with AccumulatorParam that has no equals/hashCode *** FAILED *** java.io.NotSerializableException: org.scalatest.Assertions$AssertionsHelper Serialization stack: - object not serializable (class: org.scalatest.Assertions$AssertionsHelper, value: org.scalatest.Assertions$AssertionsHelper@3bc5fc8f){code}
> These seem generally easy to fix by tweaking the test code. It's not clear if something about closure cleaning in 2.12 could be improved to detect this situation automatically; given that yet only a handful of tests fail for this reason, it's unlikely to be a systemic problem.
>
> The other error is curioser. Janino fails to compile generate code in many cases with errors like:
> {code:java}
> - encode/decode for seq of string: List(abc, xyz) *** FAILED ***
> java.lang.RuntimeException: Error while encoding: org.codehaus.janino.InternalCompilerException: failed to compile: org.codehaus.janino.InternalCompilerException: Compiling "GeneratedClass": Two non-abstract methods "public int scala.collection.TraversableOnce.size()" have the same parameter types, declaring type and return type{code}
>
> I include the full generated code that failed in one case below. There is no {{size()}} in the generated code. It's got to be down to some difference in Scala 2.12, potentially even a Janino problem.
