Shivaram Venkataraman commented on SPARK-16581:
-----------------------------------------------

I agree that `invokeJava` is too low level. [~olarayej] Is `cleanup.jobj` 
required for some custom garbage collection policies ? Could you give an 
example use case that you have in mind ?

> As described in the design doc in SPARK-15799, to help packages that need to 
> call into the JVM, it will be good to expose some of the R -> JVM functions 
> we have. 
> As a part of this we could also rename, reformat the functions to make them 
> more user friendly.
