ResultImpl.intoMap():
@Override
public final <K, E> Map<K, E> intoMap(Field<K> key, RecordMapper<?
super R, E> mapper) {
return intoMap0(indexOrFail(fieldsRow(), key), mapper);
}
This implementation does not enforce the DataType from the key argument
upon the result. I have registered an issue for this:

There are several workarounds:
1. Fetch a Long type instead of the ULong type by using an explicit SELECT
statement
2. Collect the map manually
3. Avoid using ULong in the code generator by turning it off via the
<unsignedTypes/> flag
I would suggest 3), in case ULong is bothering you too often...
Hope this helps,
Lukas
