> Check Java compatibility for MLlib 1.4. We should create separate JIRAs for each possible issue.
> Checking compatibility means:
> * comparing with the Scala doc
> * verifying that Java docs are not messed up by Scala type incompatibilities.  Some items to look out for are:
> ** Check for generic "Object" types where Java cannot understand complex Scala types.
> ** Check Scala objects (especially with nesting!) carefully.
> ** Check for uses of Scala and Java enumerations, which can show up oddly in the other language's doc.
> * If needed for complex issues, create small Java unit tests which execute each method.  (The correctness can be checked in Scala.)
