I'm getting the following error when starting a Grails 2.1.0 app on Tomcat 6 / Ubuntu 12.04.
Error 500 - Internal Server Error.
groovy.lang.Closure.rehydrate(Ljava/lang/Object;Ljava/lang/Object;Ljava/lang/Object;)Lgroovy/lang/Closure;
This app runs fine using run-app in STS 3.0 on Windows 7 and also using Tomcat6 on Windows.
I've deployed the war manually.
I've seen a similar issue reported for an app deployed to Cloud Foundry: Error 500: Closure.rehydrate at deploying grails app on cloud foundry but nothing there is giving me any clues.
The app has worked fine previously. I've made a number of code changes recently, including installing the ElasticSearch plugin but the error in the logs is referring to building the views from the gsps.

Any clues much appreciated!
Closure.rehydrate was introduced in Groovy 1.8.5 . It looks like there is an older version of groovy in the war. Check the WEB-INF/lib directory inside your war file to see if it contains an duplicate and older version of groovy.
