Ebean/idIn Parameter not set

I am having a weird problem with Ebean.

Code:

static <T> ImmutableMap<Long, T> getFromIdToItemMap(Iterable<SqlRow> rows, 
        Callable<Model.Finder<Long, T>> getFinder, 
        String idSqlFieldName, 
        Function<T, Long> getId) {
    List<Long> tfzIds = Lists.newArrayList();
    for (SqlRow i : rows) {
        tfzIds.add((long) i.getLong(idSqlFieldName));
    }
    Builder<Long, T> id_to_tfz = new ImmutableMap.Builder<Long, T>();
    List<T> tfzs;
    try {
        tfzs = getFinder.call().where().idIn(tfzIds).findList();
    } catch (Exception e) {
        throw new RuntimeException(e);
    }
    for (T tfz : tfzs) {
        id_to_tfz.put(getId.apply(tfz), tfz);
    }
    return id_to_tfz.build();
}

Exception:

I don't understand how the tfzIds list did not get inserted into the query built by EBean.

What I tried: I added the cast to long to ensure that I don't get nulls in the list. But that doesn't seem the be the problem, the list is not read at all it seems.

The exception occurred because rows was empty... I am surprised EBean did not check for that. I solved the issue by asserting that rows hasNext() as the first statement of the method, thereby provoking a more useful Exception.
