Maybe I'm reading too much into this... but Scala arrays are always of the
"boxed" type. Does that create issues if I create a Java array of an un-boxed
type, i.e. primitive type, and try to check arr.isInstanceOf there? Or, does
the fact that the array object itself already live in scala-land mean that it's
always going to be array of boxed type?
