ListChangeEvent.Change is documented to:

" The Change may consist of one or more actual changes and must be iterated by next() method. Each change must be one of the following: [wasPremutated, wasAdded, wasRemoved, wasUpdated]"

This contract is violated when setting an empty list to a property with null/empty list as value.
