well, getProperty returns something very similar actually
System.out.println("3 " + d.getProperty("account.@rid"));
System.out.println("3 " + d.getProperty("account"));
3 v(Account)[#25:0]
3 v(Account)[#25:0]
But! I've found this!
String query = "select name, in('Employs')[0] as account,
in('Employs')[0].asString() as accRid from user where name = ?";
System.out.println("3 " + d.getProperty("accRid"));
//System.out.println("3 " + d.field("accRid"));

3 #25:0
