Are there any drawbacks in openfire framework?

I actually agree openfire has a wonderful framework. But I want to know is not improved or are improving about the framework. I am more concerned about the framework rather than specific issues.


Openfire is not a framework, it is a server and your question is rather unclear, can you reword it?

I mean openfire has a good structure. But I think there must be something ,such as the cluster module, that are improving or should be to improve.

I want to know openfire’s advantages and disadvantages overall, not it’s specific question, such as a bug.
