When I use the Grails Database Migration Plugin and run a dbm-gorm-diff (for example, after installing the Spring Security Facebook plugin) I have been getting problems like: 

Error: Error executing SQL CREATE INDEX `FK609FD5A460CFCC39` ON `facebook_user`(`user_id`): Incorrect index name 'FK609FD5A460CFCC39'

It looks like the index in question is both a FK constraint and is then reused as an index later in the generated upgrade script. If i change the name, thus removing the duplicate, everything works fine. I am using Mysql. Am I doing something wrong?

Thanks.
