    I got a error while disabling a server with LilyPad-Connect v16

    CB 1.5.2-R0.1 BETA

    Code (text):

    2013-06-20 19:58:36 [SEVERE] Error occurred (in the plugin loader) while disabling LilyPad-Connect v16 (Is it up to date?)

    Seems to me that there is no harm, but still want to post it here.

    It looks like this error is caused by Bukkit itself?

    I'm getting this on all my servers on disable too. Just took a look at the onDisable source and I can't really see anything that could be causing it. The only thing that could cause the concurrent exceptions could be stopping the connect thread.

    Code (text):

                if (cloader instanceof PluginClassLoader) {
                    PluginClassLoader loader = (PluginClassLoader) cloader;
                    Set<String> names = loader.extended ? loader.getClasses() : loader.getClasses0(); // Don't warn on deprecation, but maintain overridability

    >>>                for (String name : names) {
                        if (extended) {
                            removeClass(name);
                        } else {
                            removeClass0(name);
                        }
                    }
                }
     
    Seems to be a bug in Bukkt. Nonetheless it is something that should be fixed.

    This is still existent and quite annoying for that matter. I wonder what we can do to fix this.

    I know it has to do with the massive Netty library we package in with the plugin.
