How to get a hazelcast instance in plugin?

Hello everyone, I am running my server on Openfire 3.10.0 with Hazelcast plugin 1.3.3

I am trying to develop a plugin that supports clustered environment, on the official documentation I see that you can use distributed map to share data between nodes:

http://docs.hazelcast.org/docs/3.3/manual/html-single/hazelcast-documentation.ht ml#map

I wonder how would I be able to get a hazelcast instance under my openfire plugin? (HazelcastInstance hzInstance = Hazelcast.newHazelcastInstance();)

Is there any official plugin that supports hazelcast that I can get some hints? Or maybe any experienced dev that can answer my question?

Thank you in advance.
