> It would be nice if Avro arrays were better integrated with Java collections.  The GenericArray
interface permits array element reuse, which is awkward with java.util.Collection.  But if
GenericArray implemented Collection and the Avro runtime permitted arbitrary Collection implementations
to be passed for Arrays then it would simplify many applications.  The runtime could still
reuse elements if an array implemented GenericArray, so performance would not suffer for applications
that, e.g., loop over a data file, reusing instances.
