Filing this for mongo even though I'm pretty sure it is in the core datastore mapping classes:

{noformat}
SEVERE: The web application [/mws] created a ThreadLocal with key of type [org.grails.datastore.mapping.core.SoftThreadLocalMap](value [org.grails.datastore.mapping.core.SoftThreadLocalMap@1bc475]) and a value of type [org.apache.commons.collections.map.ReferenceMap](value [{com.example.User : 4fc29ccba2437de652de0cae=false, com.example.UserRole : 82=false}]) but failed to remove it when the web application was stopped. This is very likely to create a memory leak.

Any thoughts on how to workaround or where I can access the validation maps for each domain class centrally? I realize this probably is the exact same problem Burt blogged about awhile ago with the domain class plugin maps. I can provide the link if you don't know what I'm talking about.
