The endpoint "http://api.kasabi.com/dataset/italy/apis/sparql" is not working

It seems that the endpoint 

```
'http://api.kasabi.com/dataset/italy/apis/sparql'
```

which is used in several cases of SPARQL tutorials, is not working any more. Running the code will throw 
```
java.lang.Long cannot be cast to java.lang.Integer
```
exception, can anybody provide an option to this or if there exists already some solutions that I didn't follow ?
