How to convert exception catching code from java to scala using intercept ?

From reading http://www.scalatest.org/getting_started_with_fun_suite it seems to be recommended to use intercept when catching exceptions. In the exception catching code below I need to access the Exception type so as to check its type within the
assert :

catch {
          case me : MyException => {
            assert(me.getDetail.getClass() === classOf[GenericException]);
          }
        }

This does not seem to be possible using intercept as below code causes a compiler error : ‘forward reference extends over definition of value exception’

Here is the converted to scala catch block :

        val exception = intercept[MyException] {
assert(exception.getDetail.getClass() === classOf[GenericException]);   
    }

The error occurs on line

assert(exception.getDetail.getClass() === classOf[GenericException]);

Well your definition of exception is circular. What you want is:

val exception = intercept[MyException] {
   <your exception-throwing code here>
}

assert(exception.getDetail.getClass() === classOf[GenericException])
