Which PR are you referring to?
The Hazelcast plugin integrates deeply with the Openfire core to provide low-level support for object serialization, caching, etc. We need to be very careful with changes to the PluginClassLoader, including extensive testing to ensure that existing plugins are not adversely affected.
I want to achieve a new cluster support plugin use apache ignite.
And Openfire can chose witch plugin to support clustering.
First I need support plugins resources classes can isolate ,to ensure the clusteredCacheFactoryStrategy may have implemented in different plugin.
Second is Admin manager page can chose plugin to start clustering
Then create apache ignite clustering plugin Apache Ignite
