Workaround: grails -noreloading run-app

I have the same issue. Another workaround is to delete the .slcache folder in your grails home folder.

It will allow you application to work properly and reload for a while (until you perform again the operation that got you the problem in the first place). I have not figured out what it is that is causing the problem.

I've seen GRAILS-9952 was a Grails bug that could be related: it has been marked as fixed exactly for grails 2.1.6 and 2.2.3. I suppose the workaround proposed by Vincent could be connected to the fact that the .slcache folder could be stale if you previously used a version of grails affected by the issue. i.e. see http://jira.grails.org/browse/GRAILS-9952?focusedCommentId=75947&page=com.atlassian.jira.plugin.system.issuetabpanels:comment-tabpanel#comment-75947

I can indeed confirm that this issue can by solved by periodically clearing the stale .slcache folder
