Contributing these tests in Java would make the module bi-lingual, potentially confusing future contributors Why?

Don't create separate test suites. Put them in the same class path - e.g., src/test/scala - you can have .java files in here too, they will be compiled together, run together, can reference one another. > > Cons for migrating the contribution from Java to Scala: > - there are contributors that are not familiar with Scala or are more proficient with Java(such as mlinhard).

So IMO if there's a choice between scala and java (in the scope of the scala modules) we should stick to Java wherever possible (such as this contribution). That should not be a hard and fast rule for all modules. I agree that some modules (like core) should just stick to Java.
