Abstract class not working with mongodb but working with hibernate

`abstract class BaseDomain {

```
static mapWith = "mongo"

transient springSecurityService

ObjectId id
def Long version
def Date createdOn
def Date updatedOn
def Long createdBy
def Long updatedBy

static constraints = {
version display:false
createdOn display:false
updatedOn display:false
createdBy display:false
updatedBy display:false
}

static mapping = {
sort updatedOn:'desc'
}

def beforeInsert = {
initDefaults()
return true
}

def beforeUpdate = {
def currentUser = springSecurityService.getCurrentUser()
updatedBy = currentUser ? currentUser.id : 0;
updatedOn = new Date();
}

def beforeValidate = {
initDefaults()
return true
}

def afterInsert = {
}

def afterUpdate = {
}

def afterDelete = {
}

def onLoad = {
}

def afterLoad = {
}

def dynamicProps = [:]
def propertyMissing(String name, value) { dynamicProps[name] = value }
def propertyMissing(String name) { dynamicProps[name] }

void initDefaults() {
def currentUser = springSecurityService?.getCurrentUser()
if (createdBy == null) {
createdBy = currentUser? currentUser.id : 0;
}
if (createdOn == null) {
createdOn = new Date();
}
if (updatedBy == null) {
updatedBy = currentUser? currentUser.id : 0;
}
if (updatedOn == null) {
updatedOn = new Date();
}
}
```

}`

This is my abstract class presented in src/groovy. if i am extending this class in my domain class i am getting the exception when i am trying to run the app. the same code is working with hibernate. but i am facing this issue with mongodb plugin.

The report uses an abstract BaseDomain in src/groovy with static mapWith = "mongo" and fails while constructing grailsDomainClassMappingContext. Start by reproducing the inheritance case with MongoDB, then trace the null during mapping-context initialization; done when the application starts with the abstract base class and the Hibernate behavior remains unaffected.
