The problem was caused by a setXXX(List l) where the programmer is not storing a reference to the RemovalAwareList, but creating a new list with the contents. Then, when using getXXX(), the returned list isn't the RemovalAwareList but a java.util.ArrayList.
I think this is not correct, but this is not occuring in older OJB releases...
