Description

I have a clean Grails project with the following changeset where the Groovy jar is the latest build of 1.1 final:

the project i have has the following svn changeset
A lib/groovy-all-1.1-final-SNAPSHOT.jar
D lib/groovy-all-1.1-rc-1.jar
M bin/startGrails

When I run any Gant script in Grails (such as grails list-plugins) that depends on a W3C DOM class i get the error

java.lang.LinkageError: Class org/w3c/dom/UserDataHandler violates loader constraints

It appears to originate from a MetaClass look-up. This was not a problem before upgrading Groovy.
