"Unloading plugin JAR file lib/*.jar" spam in console

I’ve developed an Openfire plugin for Apple Push Notifications (for internal use only). I’ve used some external libraries and put them inside the lib folder of the JAR. The plugin works fine, but my Info-Log always get spammed with:

2014.01.23 15:52:24 org.jivesoftware.openfire.container.PluginClassLoader - Unloading plugin JAR file /usr/share/openfire/plugins/apnsplugin-1.0.0/lib/apns-0.2.3.jar

Do you have any idea why this happens?

Most likely your plugin is being reloaded because the date on the plugin jar file is out of sync with the date on the OF server you have loaded it. OF will remain in an endless load/unload loop because the date on the plugin folder is older than the date on the plugin.

Happens to me everytime I deploy a plugin developed in the UK unto a server in the US

My solution is to always touch the jar file before deploying
