need some help with freaky template

hi community,

some of you probaly know about javolution and its iteratorless iteration.
this is how you iterate over a map:
for (FastMap.Entry<A, B> l_entry = m_listeners.head(), tail = m_listeners.tail();
(l_entry = l_entry.getNext()) != tail;) {
}

right now, idea refuses to guess the types of A and B. how can i fix this?
