Hi Patrick, Ondra,This issue could be reproduced in my local dev environment. After digging into the Java SDK, the issue probably is caused by getting the wrong method to invoke.Although the `DiskService.GetResponse` defined in API model has only a single @Out (getter) method `Disk disk()`, the Java SDK generator adds a additional setter method `void disk(Disk disk)` in `DiskService.GetResponse` class. The code here [1] use `getResponse.getClass().getDeclaredMethods()[0]` to fetch the method for getting the Disk, while it actually get the method `void disk(Disk disk)`, which obviously produces the `wrong number of arguments` error.This issue also affect fetching list of objects via `connection.link()`. I could get this fixed and commit a PR in gerrit soon.Please correct me if I'm wrong or missing anything. Thanks.On Fri, Sep 7, 2018 at 4:35 PM Geschwentner, Patrick <patrick.geschwentner@mindbreeze.com> wrote:More details:
