Rails - Apr 2014 - [rails 4.1] weird behaviour in rails console? lazy loading of database connection or spring?

I guess I am the only one using it like this, by i regularly start my 
`rails console` to quickly show the column-names of models. 

Since 4.1 (afaik), the first call to a class does not return the model 
introspection, but instead urges me to use `Batch.connection` to establish 
a connection??? 

If I use a specific method to get the column names, I get no error, and 
afterwards the class introspection just works. 

Of course this is no biggie, but I am curious what the cause is of the this 
behaviour, whether this is intended or not, and how I could circumvent it. 

Example console output: 

```
Loading development environment (Rails 4.1.0)
 :001 > Batch
 => Batch (call 'Batch.connection' to establish a connection)
 :002 > Batch.column_names
 => ["id", "name", "batch_nr",
"revision", "comments", "batch_status_id",
"created_at", "updated_at"]
 :003 > Batch
 => Batch(id: integer, name: string, batch_nr: string, revision: string, 
comments: text, batch_status_id: integer, created_at: datetime, updated_at: 
datetime)
```

Any tips or hints would be greatly appreciated.
