I'm experiencing this error periodically (about 50% of the time) when i try to restart my JBOSS server or redeploy my ear file.

My ear file consist of many .jar and .war files and for each one i can see that Hotswap Agent is trying to load the JBossModulesPlugin. It fails periodically and on random .jar/.war files each time.

After one or two redeploys, its all good. Then if i redeploy again it will fail again.

Here is the console log:
