Ruby arrays are similiar to java collections. Java arrays are static and
kind of different than collections. Probably that's why the object binding
in the java client doesn't work (like the error says: embedded type has to
be collection / map). I tried to define a custom serializer / deserializer
for custom data types, but it didn't get called :/
