BUG: the group's propties can not sharing in a cluster

there are openfire1 and openfire2 in a cluster(hazelcast).

i try to reset a group’s property which key is “testKey” on openfire1. note: i use Group.getProperties.put(“testKey”, newValue).

but then, i can not get the newValue in openfire2.

i search the openfire_3_8_2 source code and found the reason, there is not sync the group properties in the cluster cache.

it is a bug? if not, please help me to sync the properties.

If you are doing this from a plugin, use a network cache to sync cluster nodes
