Running Openfire 3.4.5 on CentOS 5 (64bit) with Email Listener Plugin 1.0.0 installed, I cannot remove the plugin via the admin console.
If I try, the admin console tells me “Plugin deleted successfully.”, but in the Openfire debug.log I see this:
2008.03.09 09:00:29 PluginManager: Unloading plugin emaillistener
2008.03.09 09:00:30 PluginManager: Loading plugin emaillistener
2008.03.09 09:00:50 PluginManager: Extracting plugin: emaillistener
And the plugin is still running. The only way I was able to uninstall it was by removing the plugin’s .jar file and directory via SSH and restarting Openfire.
