Java exception GatewayPlugin cannot be cast on plugin restart

Openfire Plugins Kraken - IM Gateway
1

Running openfire 3.5.2 with IM gateway 1.2.3 on windows 2003 r2 sp2 32bit using LDAP (AD) as the user auth.

If I restart the plugin, I get this on the server/gateways section:

If I do a full restart of openfire, I don't get the exception. Its only when I restart the plugin.

Any ideas?

Thanks,

Wow. Hrm. When it’s in this state, can anything else be used? In other words, can clients access their gateway accounts?

The internal communications still work fine. I don’t know if communicatiosn through the gateway works - I’d restarted it because of the MSN signin errors everyone is experiencing (prior to my knowing everyone was having the problem).

Once I can log back into MSN, I’ll restart the plugin and check.

Thanks!

Just deployed 1.2.3a. Was able to log into MSN. Restarted the plugin, waited for the green bar “plugin restarted”. Still get the java exception, but yes, users can connect and send messages through the gateway.
