Your visions accounted for what I am today and what I believe in. Thank you.

		<description><![CDATA[If you suddenly experience problems callling set.remove() and set.contains() on your Java Set instances, you might be using Hibernate, which replaces your Set instance with its own version (PersistentSet), which uses a HashSet internally to store your data.

		<description><![CDATA[Ok, this just took me a while to figure out so I thought I'd share it here.

If you have a boolean variable that follows the naming convention "isValue" (e.g. boolean isPerson = false;), then the according mapping file property name may not include the "is" part of the name, for example:
