Just found the answer, and luckily in my case it was simple to solve.... I have a subtype of List<T> called PageImpl<T>, which had another List<T> containing the page items, plus the total count. Then (and I think is a problem in GWT compiler), the compiler resolves FocusListenerCollection, which extends ArrayList<FocusListener> to be a subclass of List<T>. As a result, ALL occurrences of Collection of anything in any RPC method, by having PageImpl as a subclass of collection, had added those ListenerCollections as possible result types, generated code to handle them (50k in my case) and issued the warnings. The solution (in better words: hack) was to change PageImpl to not have a List of page items, but a LinkedList (it then converts the receiving list into a LinkedList, which is even a penalty in my case). As no ListenerCollection extends LinkedList, the problem is gone.
Ah, I also had an RPC which result type was List<List<String>>. The same problem. As it was just for testing, I changed it to List<String[] >. But I'd really want to hear from a GWT dev if this is not a bug in the compiler...
