I’m seeing the following ClassCastException when I try to access users/groups from the console.
The problem is only seen when clustering is enabled.
I enable clustering via openfire.xml edited with: true
Using the console to enable clustering results in https://igniterealtime.org/issues/browse/OF-1045 so editing xml is my only option.
Here is the ClassCastException:
HTTP ERROR 500
Problem accessing /user-summary.jsp. Reason:
Server Error
