while I agree with the code change based on the current implementations of
getVirtualSize, should we just pass the storage layer in the params so that any
new implementation if required can use the storage layer?
```
Map<String, Object> params = new HashMap<String, Object>();
params.put(StorageLayer.InstanceConfigKey, _storage);
processor.configure("template processor", new HashMap<String, Object>());
```
