HQL exception when calling ChangeRequestStorageManager.countChangeRequests(false)

When calling ChangeRequestStorageManager.countChangeRequests(false), DefaultChangeRequestStorageManager.getAllChangeRequestQueryStatement(false) is called, the following line then produces an extraneous comma before where:

statement = String.format(", BaseObject as obj , StringProperty as obj_status, " + "where doc.fullName=obj.name and obj.className='%s' ", this.entityReferenceSerializer.serialize(CHANGE_REQUEST_XCLASS));

Which in turns causes an HQL Syntax error.
