Plugin dev, how to get presence property?

Hello,

I developped a Jabber client with Smack. I mark presence packets with some properties with Presence#setProperty() method.

I’m now trying to develop an Openfire plugin that read that property but Presence#getProperty doesn’t exists. How can I access my presence’s properties?

Thank you for the hint!
