Here's what's happenning at the moment: A transaction: - put some data in the cache. Another transaction: - modify its definition -> remove() is called - update its value -> put() is called with the new value The problem is that if I call get() on that node between the remove() and the put(), I still obtain the old value, but shouldn't I obtain null??
