Fix for OPENAM-2536 (a.k.a. OPENAM-139) - review: CR-1859
Due to the fact that the JAX-RPC interface never actually gets the isString
parameter, I've ended up creating a new method on the interface, this way
old versions of clients should still be able to retrieve non binary
attributes. The binary data is being transferred in a Base64 encoded format
to the client, where the client needs to decode and recreate the
Map<String, byte[][]> structure.
