I put in a fix which avoids the NPE. I haven't had time to craft a suitable 
standalone test yet. Leaving open until a test is added.

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 
bound = org.grails.datastore.gorm.AbstractGormApi  -> 
org.grails.datastore.gorm.AbstractGormApi 
name = D
classNodePlaceholders = {}
redirectBoundType = null
{code}

Seems to be caused by this method:

{code}
@CompileStatic
protected  List 
getInstanceMethodApiProviders(Class cls) {
[getInstanceApi(cls), getValidationApi(cls)]
}
{code}

Removing `CompileStatic` solves the issue
