Meaningful error messages when lifecycle functions return something other than system #12

Open michaelklishin opened 10 years ago

michaelklishin commented 10 years ago

When a lifecycle function (e.g. start) returns something other than system by mistake, you get really obscure exceptions from Jig runner.

It should validate the returned value and complain if it is not what's expected.

Yes, that's a problem that's bitten a few people, including myself a few times. The solution may be to have start return a value, rather than the system, and limit access to the system map.
