Openfire supports properties, which are hierarchical. For example:

• root

• root.child

• root.child.grandchild

When a property is deleted, its children are too. Removing root.child would also cause root.child.grandchild to be removed. Removing root would cause all of these properties to be removed.

There is a nuance to this. The implementation removes all properties of which the name starts with the name of the property that is being deleted - no separation characters are taken into account. This means that in the example below, removing root would still remove all of the properties.

• root

• rootchild

• rootchildgrandchild

As these properties do not clearly live in the same hierarchy, that can lead to unexpected issues. Openfire should take a separator character in account when removing properties.
