If you turn on logging, then you can verify exactly what's coming back

I will perform some deeper debugging, also in the driver code.

My guess is that something's not quite right in your Service class.
groupBy works best when there is a very simple getter/setter for the
list.

I'm sorry, I should have provided these informations on my previous messages. Yes, I do have simple (autogenerated by eclipse) getter and setter. In the specific case of 'tagList', they are

public List<Tag> getTagList() {
    return tagList;
}

public void setTagList(List<Tag> tagList) {
    this.tagList = tagList;
}
