------------------------------------------------------------
I haven't worked out why yet, but some debug info at the point where the
exception occurs. I had trouble trying to replicate with a simple
self-contained example.
{code}
classNode = org.grails.datastore.gorm.AbstractGormApi <java.lang.Object>
bound = org.grails.datastore.gorm.AbstractGormApi <D> ->

classNodeType = java.lang.Object (previous value:

name = D
classNodePlaceholders = {}
boundPlaceHolders = {D=D}
redirectBoundType = null (previous value: D)
